    87 350 TBI running lean

    I have a 1987 350 tbi truck that runs a little weird. When I put it back in park after driving it for a while, it shoots up to around 1600 rpm and slowly comes back down. Also just changed all the plugs and they were white. Driving around monitoring the sensors shows that the BLM and INT are...

    1987 350 TBI code 42

    I have owned my 87 chevy for over 2 years and I have had a code 42 for most of that time. From what I know this means that the ecm is not talking to the spark module on the distributor? I have just run my truck with this code forever because it has always run fine. Now I am having issues and I...

    K10 Misfiring

    I have an 87 k10 that has started misfiring recently. When I first turn it on and I am driving it around it runs fine. Once it warms up it starts to misfire at throttle under load. When it's in neutral it doesn't do it. It is especially bad when I am going up hills and it gets worse as the truck...

    1987 4WD Slip Yoke Leaking

    1987 Chevy 4WD 700r4. My slip yoke is leaking from the center plug thing. From what I have read the 4wd models have the spline missing instead of having that seal and hole in the middle of the yoke (you can see mine has no weep hole). Is the best option to just replace the whole slip yoke?

    350 TBI high idle

    I have a 1987 K10 with a TBI 350. I discovered a mistake in the wiring and fixed it and adjusted the idle properly. Now, when I start the truck up it idles at around 1000 rpm and when I switch it into drive and back to park it starts to idle at 1700 rpm. What do I do?

    1987 K10 Idle issues

    I have always had issues starting my 1987 k10. I would always be really rich and idle low and be almost impossible to start in the cold. Then, once warmed up, it would idle way too high. it had codes 15 (low coolant temp), 32 (barometer error) and 42 (?). I finally bought a obd reader and hooked...

    '87 TBI Rough Cold Start

    Hello! I have an 87 with a 350 TBI that really does not like to start in the mornings when it is cold. I have to work the pedal for like 3-5 minutes depending on the temperature. When it is warm it runs fine. What could be wrong? The tube that comes from the exhaust manifold to heat the air is...

    ECM Interchangeability

    Hello! I need an ECM for an '87 350 TBI. I have access to 90'-93' ECMs that are in 350 TBI c1500s. Would these work without modification?

    Flooding issue

    Hello Guys! I have a 350 TBI that injects way to much fuel to the point that the truck will not even start when I crank it. When I unplug the injectors, the truck runs fine until there is no fuel in the manifold. I read that this could be a coolant temp sensor. I replaced that and it did not...

    Possible flooding case

    Does this look like too much fuel spray to you guys? I have a possible flooding case. Don't look at the wires going to the injectors or the melted injector plugs lol

    Hello! I am having issues with my 1987 K10 (350 TBI). I have access to a 1995 G20 van that also has a 350 TBI engine. Are the ignition and computer parts on theses engines compatible with each other? Thanks!

    Weird no start

    Forgive me for another no start thread but I have a weird issue. So a while ago a battery went dead in my 1987 k10 (350 tbi). I went and got a new battery but it would not start. One day I went out, tightened the battery connectors, and it started up like nothing had happened. It was running...

    Leaking Slip Yoke

    Hello Guys! I have a slip yoke that is leaking out of that plug thing in between the ears. Is it alright to simply brake clean this and RTV it? What is the point of this plug if it is alright to RTV it or weld it? Thanks

    1987 K10 No start

    Hello! About a week ago I accidentally left my lights on on my 1987 K10. When I came back to it it was stone dead. I tried jumping it to no avail. I took a battery out of a family member's '90 blazer and it fired right up. I then drove it home, got a new battery in it, and now it won't start. It...
