Question about 1992 Chevrolet K1500
I did a tune up to my truck, then the timing chain went out, I put a timing gear set in, it ran good on the dirt roads, but once I got on the hwy and hit 75 mph, it bogged down real bad, I have no power, can't go over 45 mph, it revs up hi to get speed and it shifts down easy some what, but when it shifts back up and the rpm goes down, it shifts hard, like it slams in gear. I think I knocked out a sensor but don't know for sure and I can't get any help from anyone, and I can't afford a shop just yet.

Check and make sure your vacuum lines are all connected, even the air breather.

Hi, yes I just had the same problem and the clutch packs inside the transmission are slipping. I had to replace all the clutch packs as well as the bands. The parts for this job really aren't that expensive. you could get everything you need for less than 300 bucks. however labor is where they kill you. It's about a 10 hour job or maybe 12 depending on application. average shop rate 80 an hour you looking at 900 dollars labor plus parts. if your mechanically inclined and have tools you could take your time and do it yourself. you can buy a step by step DVD for your specific application. other wise I would call around to transmission shops. their is a slight chance it may also be your solenoid pack. the best way to confirm is to have a transmission line pressure test done. I hope this helps!

your exhaust IS plugged. you need to find out where. the cat would have been first however in this case.....what else in down line from the manifolds?

In most cases problems with idle speed involve the idle air control valve or a dirty throttle body. The computer controls idle speed by how much air is allowed into the intake thru the control valve.
If the throttle is not sticking, I would check the valve and the bore of the throttle body.
You could also have a vac leak but that would usually be a constant problem.
