Engine/Transmission (1994 - 1998) Starting

[JoshPeters]

Alrighty... . last fall I put in Piers Diamond B 370's. I love'm. The truck has started better this winter than last... . no problems till..... Last weekend a friend bought a car in Southern Wisc. It was about 610 mile round trip. The truck pulled very well, as I expected, but I was in a bit of a hurry on the way back. I was runnin 80-85 with this 89 Caddy on the trailer. EGT's were in check. Ever since, the truck starts normal when it's cold, but as soon as I touch the throttle it starts to miss. I've let it run for 2-3 min at a slightly elevated idle (1100rpm) and it doesn't seem to help. Once I pull out of the drive way and get a load on it, it'll miss till the turbo comes up then it clears out and runs great. It didn't do this before I pulled that car back... did it get hot and I didnt' notice it? I'm not loosing coolant and the oil looks normal.

Timing???

Any chance the timing might have backed off a little.



When it gets cold (like weather you will get in the next day or so) stock or slightly below will run rough on a cold engine. It will start the same. The 370s would only make retarded timing worse in cold weather.



Just a guess.

I'm going to re-time it here pretty soon. Last fall (about a year ago) ChillyDog and I timed it and it was set to 16. 5. It didnt' help the starting but it sure ran better! (timing had slipped to about 10 degrees!)
