    1995 K1500 LS swap or TBI Rebuild + Exhaust

    I’m fairly capable and can assemble the engine myself and I do know of a good machine shop in my area. If I’m taking the time to take the engine out, I would rather go through it and do some much needed power upgrades to make the engine a little more fun. There are quite a few junkyard TBI 350’s...

    I do have shorty headers. That y pipe looks like it may work.

    1995 K1500 LS swap or TBI Rebuild + Exhaust

    It is my current daily driver, but I do have a 1979 Cutlass with a 455 I wouldn’t mind driving as my daily again. I’m not entirely sure how the oil is getting in. It doesn’t puff on start up and smokes the worst when you are using engine braking or when you floor it and then let off. The...

    1995 K1500 LS swap or TBI Rebuild + Exhaust

    I need some general advice and opinions. I have a 1995 K1500 with a TBI 350 in it that oil fouls cylinder 6 quite often. I’m thinking of either tearing the engine down to the short-block, inspecting the cylinders, replacing the heads, cam, lifters and putting in a timing set and putting it back...

    Ac Delco, not that, that means much anymore.

    1995 K1500 TBI 350 Running Rich

    I have an update. I unplugged all of the sensors one by one and the only difference was unplugging the CTS while running. It wouldn’t flood out the engine that way. Could I have gotten two bad CTS’s in a row? Could the grounds be at fault?

    1995 K1500 TBI 350 Running Rich

    I read up on it a little more and it turns out I was just looking at open loop, closed loop like you said Shurkey. I’m just guessing until I get a scan tool.

    1995 K1500 TBI 350 Running Rich

    Hmm. I could be wrong. It could be just rich and lean. I’ll have to research that again. It would tell you open and closed loop as well?

    1995 K1500 TBI 350 Running Rich

    it’s a ‘95, so it should be heated. Cross counts are two at idle in 10 seconds and 4 when driving in ten seconds. I jumped pins an and b that’s how I’m getting the cross counts without a scan tool.

    1995 K1500 TBI 350 Running Rich

    I noticed something. The O2 sensor is lazy when it’s hot and idling as well, but not when it’s driving. Is that a symptom?

    Sorry, I misread your comment. I’ll try disconnecting the sensors and see if anything changes and I’ll post the results.

    1995 K1500 TBI 350 Running Rich

    I sadly don’t have a scan tool just yet, but I will do some testing when I do get one. I’ve replaced the coolant temp sensor twice, but I’m not a fan of shotgunning parts at it.

    1995 K1500 TBI 350 Running Rich

    I tested it while it was warmed up. Sometimes it’s lazy, other times it isn’t. For example if you start it after its been warmed up and you shut it off the cross counts will be high, but then once you drive it they’ll stay rich for a few second then lean, etc.

    1995 K1500 TBI 350 Running Rich

    It’s pig rich when it’s cold to the point that if you give it a little gas it will stumble because it’s flooding.

    1995 K1500 TBI 350 Running Rich

    1995 K1509 I don’t have a scan tool yet. It doesn’t have a catalytic converter. All of the spark plug wires and components are a year old and the timing is set per factory spec to 0°btdc with the est wire disconnected.

    If that’s the case it’s definitely lazy.

    1995 K1500 TBI 350 Running Rich

    Hello. I’m having an issue where my TBI 350 is running rich when cold and if you rev it a little it will spray a ton of fuel out of the injectors accompanied by black smoke. It runs fine when it’s warm. I recently replaced the intake gaskets, cleaned the EGR valve and replaced the CTS. Fuel...

    TBI injector harness grommet.

    I'm having trouble sourcing this grommet as mine has become brittle. Does anyone know if any companies reproduce them? Also, does anyone know what kind of terminals are used inside the injector pigtail? I imagine I'm going to have the cut the wires if I replace it. So I'm either going to put a 4...

    1995 K1500 Engine Harness Removal

    Hello everyone. I have a few questions about removing the engine harness on a 1995 K1500. I know you have to disconnect part of the harness at the bulkhead on the driver's side and that the other side of the harness passes through the firewall on the passenger side which goes to the ECM, but is...
