Hello all, This is my first post. I will try and make it quick.
I have a 1989 Chevy C1500 with the 350 TBI and 700r4 transmission.
I got the truck for 500$ because it had a blown head gasket. When i got it, it cranked and ran fine. just with the blown head.
My friend who said he knew what he was doing helped me.
Long story short, it does not run by itself anymore.
We replaced all the gaskets, timing, water pump, and did a tune up.
We can start the truck as long as you give it 1/2 throttle. if you take your foot off the gas it dies.
if you keep gas on it it will stay running until you uncrank or take foot off gas.
1. I verified that all the vacuum tubes are connected correctly.
2. everything is torqued down to spec.
3. compression on all cylinders was within specs
4. TBI is getting fuel
5. Spark plugs are getting spark
I am not sure what direction i need to look.
I think it could be a tooth or few off on timing. But i was told that even if it were off on timing that the truck would still idle.
What do i need to check for no idle?
I look forward to getting some good help.
Thanks!
