bumo i just went out and rechecked the dizy firing order and it was wrong i fixed that it idles good now now it just is lacking power im assuming the cams are off alil, and i do have a vacuum leak do you think that would cause it to have low power and pop back threw the intake alil bit...

do you think if i timed the crank by using a screw driver in the num1 cylinder but i was turning it clock wise and not counter clock wise it would throw the timing off one tooth and cause it to lack power.....

make sure you don't have the connector for iacv switched with another from the harness, some sensors share the same clips and i think (but i'm not sure) the iat sensor is one of them.

my car threw a cel and idled like **** when i had these switched around, the tps and map sensor connectors can also be switched around ....

i tryed swithching the tps and map around and it idled fine then if i gave it gas it back fired bad also i am only throwing a code for the iacv which is not hooked up, if the plug was wrong for the ias im sure it would throw a code to......

? iacv is not hooked up, how do you expect it to idle if it isn't sending anything to the ecu? Did you build a blockoff plate for the iacv or is it just hot plugged in?

yea its not plugged in because when it is it idles at 4000 rpms constent so do you think this might be why it idles funny........
