    Questions on Misfire for 98 Burb with 7.4l

    Who knows. The upper control arm they showed me was shot. Ever since the kid took over the shop full time it has gone down hill. Overall will never go back. New shop said they will let me know what they find out. I told them what I know; Leaking Lower Intake Hot Start Issue Misfire on 3...

    Questions on Misfire for 98 Burb with 7.4l

    No they are not. Granted I paid with a credit card but they didn't charge anything for the theory my block is shot. Just the charges to replace the upper control arm on the driver side and the tune up. If it comes back that it is injectors then I will be asking for money back. They keep...

    Questions on Misfire for 98 Burb with 7.4l

    Well got it back. Still no official quote on a cost of an engine. Also it doesn't look like they pulled the pan, or anything underneath. All the bolts have a nice sludge covering from the leaking oil cooler lines. They didn't even put the parts in the vehicle. I had to go back in and ask...

    Questions on Misfire for 98 Burb with 7.4l

    The way I vest a mechanic is start off with stupid simple things. Oil Changes, inspections and any repairs that are critical. I think the shop has gone down hill since the son took it over. Most people I know have said the same thing, the last year they have been horrible. I don't have...

    Questions on Misfire for 98 Burb with 7.4l

    I am taking it to the one my employer uses (downside they are 50 miles away). I am going to pull it out of the shop today and tomorrow take it to them. They are squeezing me in for a diag since this is been going on for a better part of 2 months. The vehicle original went in for a Misfire...

    Questions on Misfire for 98 Burb with 7.4l

    Well I have had it back at the mechanic since I had a friend tell me that it sounded like it was a valve issue (either sticking or damaged). Two weeks later the mechanic is telling me it would be a waste of money to rebuild the upper end since the motor has 200k on it. He was telling me that...

    Questions on Misfire for 98 Burb with 7.4l

    When it comes to price. I rather pay out the nose once and have a reliable vehicle. I use this as our off road rig, camping and hunting vehicle. So rather it not break down 100s of miles from the house. I am looking at the two options still. There is the new...

    Questions on Misfire for 98 Burb with 7.4l

    The hot start is as you described. Frost came about when I replaced the fuel pump and filter. Really annoying to have hot start issues where it takes a few cranks to get going. The compression is consistent on that cylinder. It seems the others are quicker to get to max. When I ran it...

    Questions on Misfire for 98 Burb with 7.4l

    So another update. Pulled the wire. Still have a misfire. Lots of misfire on that cylinder. Doesn't seem to matter the RPM. The higher it does get less. New development is that I can hear a mechanical clicking noise on that side of the motor. So I pulled the plug again and tested for...

    Questions on Misfire for 98 Burb with 7.4l

    Mileage is 225K. I use Torque Pro for the app. The OBD Reader is a BAFX Products 34t5 She does leak antifreeze. I know the lower manifold has been leaking off and on. Normally if the truck is only ran for short amount of time she weeps out the front. If I run it for a longer period of...

    Questions on Misfire for 98 Burb with 7.4l

    Just an update. Since I had all the plugs pulled. I replaced them all. Ran a can of Seafoam thru the intake. Lots of white smoke and took her out and tried an Italian tune up. She has power again. She runs great under load. Doesn't feel like she is missing at all. At idle she still...

    Questions on Misfire for 98 Burb with 7.4l

    I looked up the 5-0 Motorsports injectors. While this doesn't sound horrible to accomplish the reality is till the fires are over here in the PNW working out side is almost out of the question. Currently we are getting a few inches of ash falling everyday.

    Questions on Misfire for 98 Burb with 7.4l

    I am going to go get a fuel pressure tester on loan tomorrow. This was one of the tests I asked to be completed due to the hot start issue the vehicle has. I am guessing it is bad due to pulling the Air Cleaner and it has a strong smell of fuel. What he told me was that it was a dead...

    Questions on Misfire for 98 Burb with 7.4l

    Evening, I think my mechanic is either not interested in working on this vehicle anymore or is trying to screw me out of a few thousand dollars. Last month on the way back from the coast lightly loaded we started to have a misfire and rough idle on the bus. It was missing the heatshield on...

    4x4 Light Flashing Light randomly

    Okay an update. Still no idea on why it does what it does. This last weekend if I stopped and shut off the car it was a crap shoot if it would show it was in 4x4 or not. Scenario. Running around in 4x4 high. Stop go pick some berries and look for a grouse. Come back and start the truck...

    4x4 Light Flashing Light randomly

    I have had this odd issue with my 98 K2500 with the push button transfer case. It shifts into 4x4 fine (Auto, Low, High). Runs around great and will shift out fine as well. The issue is sometimes (random as far as I can tell) when I am in 4x4 high or low the light will start to flash. It...

    454 Vortec help

    I unplugged my Air Pump and I haven't gotten the check engine light. I had to unplug it due to a growling bearing and since they 454 Pump is no longer in stock anywhere good luck finding one. I was going to remove mine but the belt routing was different. I was going to purchase an alternator...

    Fuel pump snap ring problems.

    I replaced my pump last fall and didn't get the gasket/snap ring in the right spot. Filled it full and it popped the fuel pump up and the gasket fell into the tank. I ended up ordering a Spectre kit that came with a new gasket and ring. To get it on I started it on one side, and moved notch...

    Not too happy

    On the fuel leak, it might be the pump main gasket. Mine messaged after I changed it last fall. Pulled it on the fourth and it wasn't on the pump assembly. The new gasket and pump took more effort in fitting. I only replaced the Pump the second time around due to breaking a fitting in the removal.

    The Stupid Engine Questions Thread

    It isn't the diesel just the big Vortec 7.4l. Idle RPM is at rest (Park or Stopped) is around 800. My question was is it normal for the torque and size of the motor on a flat basically keep it moving at 30mph with around 2k rpms without much input on the throttle.

    The Stupid Engine Questions Thread

    Just a question regarding my Burb. Took it off-road this weekend and it was the first time I ever tried to wheel it. Is it normal for the 7.4l to basically cruise in drive without much throttle at around 30mph? Was on some flats in 4x4 high and could just let off the gas and it would just want...

    98 K2500 Burb with 454 Smog Delete

    That is the part that I need. I found one and almost had it removed from a local yard. It seemed to be stuck on the stud and I couldn't get it pulled away from the motor. For now I have just unhooked the electric clutch and it no longer makes the grinding noise. Just want to have a backup...

    98 K2500 Burb with 454 Smog Delete

    I think I have figured this out. I will need to source an Alternator Bracket from a 1996+ GMC/Chevy 454. I found one in the local yard now just about getting it pulled. I noted that they did two bolts and one threaded on stud...why couldn't it just be another bolt.

    98 K2500 Burb with 454 Smog Delete

    That was what I was seeing, the issue is I have no idea what that area on a non smog truck looks like. It is possible they have the correct bolt, and mount there or it was a different alternator bracket. I need to pull my truck in and see what is all around that tensioner. Would be great if...

    98 K2500 Burb with 454 Smog Delete

    True, finding one for the 454 is little harder. Plus how long will a used pump last before I am once again trying to dig up another. I might just pull the electrical connection to it and leave it be. It only makes noise when the clutch is engaged. I know the pic n pull has a 454 truck (only...
