#390 of 449 1990 Chevy K15 BIG PROBS by johndawkins Feb 19, 2007 (7:50 pm)
ok, i have a 90' K15 4x4 with a 305 TBI 5 spd. and a little while ago i had put a new hooker muffler on, and it has a 3" inlet w/ dual 2 1/2" outlets. ok... no problems. Then about three weeks ago i bought a set of flowtech shorties and put them on. had a little trouble getting them to seal perfectly but they're fine now. But now since i put them on i have noticed a big change in performance like i don't have as much low end power and it's just not running very good. I'm a college student and am pretty broke, but any help at all would be better than what i am now!!! Replies to this message: johndawkins (Feb 19, 2007 8:24 pm)

Replying to: johndawkins (Feb 19, 2007 7:50 pm) another thing is that when i was putting the headers in, i broke one of the smog tube that goes into the header/manifold so i just removed all that stuff but still have the pump on the truck. when i unplugged my O2 sensor to see if that might be the prob, all that happened was my check engine light came on but made no difference performance wise. I NEED HELP BIG TIME!!!!!!

Replying to: sosbomb (Feb 21, 2007 2:48 pm) the Cam position sensor is on the distributor on your engine. It is basically the electronics of your distributor. On the older electronic distributors, it would have been called the pickup module.

#399 of 449 hindge pins by dmrobertson Apr 08, 2007 (4:45 pm)
The driver side door on my 2000 year 2500 series pickup is sagging. The pins need to be replaced. I have done this on other doors but a spring is in the way on this vehicle and it looks like I may need to un-bolt the door to change the hindge pins. Any suggestions?
