    1999 Tahoe 5.7L random misfire

    Hey guys still trying to fix the issue. I just replaced the injectors to the mpfi upgrade and still same cylinder 2 and 8 misfire. If the distributor is bad would it cause all the cylinders to misfire or just a couple? The cap and rotor seem fine. They were corroded a little but i cleaned them...

    1999 Tahoe 5.7L random misfire

    These are the misfire counts on each cylinder #1: 12 #2: 492 #3: 0 #4: 2 #5: 1 #6: 1 #7: 0 #8: 130 Bank 2 short term fuel trims go up +15% under load so it is going lean.

    1999 Tahoe 5.7L random misfire

    From what I read if the ignition control module goes bad it would not start? Keep the ideas coming guys I appreciate all of the help. Weird thing is that it started all of a sudden. When she drove it the day before it ran fine.

    1999 Tahoe 5.7L random misfire

    Is there any way to verify injectors before buying them? I know they are expensive and I'd hate to spend so much if it is not my problem.

    1999 Tahoe 5.7L random misfire

    1999 Tahoe 5.7L random misfire cylinder 2 and 8 Hey guys My gf has a 1999 OBS Tahoe with a 5.7L. One morning it started running rough sputtering and misfiring so I told her to park it until I have a chance to look at it. I checked fuel pressure and it is good. No vacuum leaks. Last tune up was...

    1999 Tahoe Fuel gauge always reading full?

    Been reading about the techron and gm fuel system cleaner in the tank. Is it worth a shot?

    1999 Tahoe Fuel gauge always reading full?

    The 95 cluster looked to be the same as the 99 cluster. Did the exact same thing too. Pegged to full, then empty, then full. On the rear looked identical to the 99 cluster except it said 95 c/k truck.

    1999 Tahoe Fuel gauge always reading full?

    Tried the 95 cluster and it did the same thing. I'm guessing next is the sending unit? Do the 2 purple wires go to the PCM so i could test them with an ohm meter? Ive been looking at diagrams but only see one wire instead of two at the pcm for fuel level.

    1999 Tahoe Fuel gauge always reading full?

    Any idea if a 95 cluster is the same as a 99? I went to the local pick n pull and the only one left was a 95.

    1999 Tahoe Fuel gauge always reading full?

    The fuel gauge in our 1999 2 door tahoe is pegged on full. I changed the fuel pump and sending unit about 2 years ago with a racetronix module and has been working fine until recently. At first the gauge would bounce around between empty and full but now it is just pegged at full all the time...

    Help identify this lift kit

    Was just browsing the local classifieds and came across this lift kit for sale. It doesn't say what brand it is or much else info on the kit. I will go look at it today but just wondering if anyone has any idea what it might be or if its not worth the time? Shocks look like bilstein...

    96-98 Vortec Alternator Upgrade AD244

    Can someone check and tell me how many wires go to the pigtail on 96-99 trucks/SUVs? Is it just 1 wire in the second position hole?

    Improved A/C

    Does anyone know where the fresh air comes in from for the heater? I thought it would be behind the wiper cowl but when i removed it there is only a hole on the driver side.

    Improved A/C

    So the drain is the same drain that the ac comes out of, which is more toward the square box. I am wondering how does water get into the actual round part of the blower motor.

    Improved A/C

    Can you tell me where the drain is? I cant seem to find it anywhere. Or is it the same drain as the AC uses? It always pours out water when the ac is on.

    Improved A/C

    Has anyone had a problem with the blower box filling up with water? I just pulled the blower out and there is a little puddle of water from the rain. Is there a drain that may be plugged?

    Voltage meter jumps with blinker on?

    I checked with the voltmeter yesterday and there is no actual drop in voltage. Just a funky gauge.

    Voltage meter jumps with blinker on?

    Thanks for all the info. It just started doing it a few months ago so it hasn't been an issue since new. It could be a problem with the cluster because the oil pressure gauge sticks and the fuel level gauge gets kinda shaky. But i will definitely check the voltage at the battery and fuse block.
