with all that stuff removed how is you computer not giving you a check engine light? do you have an o2 sensor in the new header? its probably not working at all or the check engine light has been removed. most guys who have gone that far replace the carb with a non ecm carb or they modify the...

without the air management system in place, and if the computer is still functioning there is a problem. my system works great. its a good system that is what makes an l81 an l81. sorry for any confusion. the performance check will not help you after the engine has been altered. replacing that...

hello. do you have the service manual. its clear on the course of action you should take. along the flow chart starting at a performance check will lead you to your problem. after the performance check move on to air management system check. plug the headlight circuit and do a performance check...

okay then. like mikey said remove the headlight circuit from the manifold and cap it to eliminate the entire headlight system from the engine. just cap that tee where you remove it. then do a system performance test. page 6e1-11 of gm manual. if you dont have this i will send it to you in a...

hi antz sound like you doing what i just got done doing. do you have a mighty vac or similar vac gauge/pump. did you spray wd 40 around the carb base gasket and the intake manifold where it meet the heads with the engine running? the dwell can be set. make sure you confirm all the leaks are...

update for anybody who cares. i have found a supplier who will sell the oem diverter relay for our 1981. he will also rebuild your existing diverter valve. i think i could do it myself and the guy is very helpful if you have questions on the rebuild or what parts you will need to use as doner...

or if anybody has just the relay that mounts on top the diverter. my diverter is okay according to my shop manuals flow chart. just the relay is testing bad. any suggestions?

carb settings hello. i had similar issue and turned out the balancer had slipped. would run but not right. then when it came to full temp it would hesitate and stall occasionally. even though i used a time light it would show it being correct but was timing to a mark that had moved.

when i go to buy new freeze plugs for the front of my engine they are all 1 5/8 both sides of water pump. mine is not. it is 1 3/4 on passenger side of water pump and 1 5/8 on driver side of water pump. reason im replacing is the passenger side was leaking. it had a hole rotted in it. it was...

I need some help. I haven't been able to work on my car lately but now im relocated in southern California and am at it again. can someone please tell me why my car runs like crap with the computer connected and runs smooth as can be when the ecm is unplugged completely. hot or cold it runs for...
