after a long winter... I just have to do a little tuning on my '97 ram w/5.9 gas!
it starts perfectly when stone cold. Drives right out. Just recently I noticed it is not upshifting to OD unless I completely take my foot off the gas. It then holds it fine after the upshift.
Then, after I get to town, (about 30 miles) it's of course fully warmed up, and the first stop light I come to, it's idling about 1100-1200 rpm in gear.
I'll pull in and park, do the errands, and when I come back out to restart, it does not start with authorty. It does not 'take off like a bird'...idle is very slow and you really can't tell it's running until you release the start switch. after revving it a couple times, it is now idling fast again. Sometimes it will kill the engine when I pull it into gear. after about 30 seconds, it is now running like normal, except for the high idle speed.
Randy thinks it's in the throttle body...needing cleaning. I did this last fall, when I replaced the plenum gasket, dist cap, wires.. etc but that was 8000 miles ago. I will give that a try first!
If memory serves me correctly, I think I re used the tb-manifold gasket.. and possibly there was an issue with it and I used some rtv on the gasket to reuse.
seeing that it starts up like a champ when cold, perhaps the temp sensor is faulty? No check engine light comes on.....
You suppose the upshift problem is related? (as in 'no upshift until engine is at a certain temp')
Thanks!
Bob
