i just installed the aem cai on my '02 rally, when i finished i started the engine. is started and then immediately shut off. after doing this a couple of more times it finally stayed on. it still has a really rough idle and shuts off every couple of starts. it also stutters when i am at 2500+ rpm's cruising. does anyone have any idea what's going on? can anyone help me? thanks

 

Reset your ECU. Disco the neg terminal on the battery for 20 minutes. Expect the ECU to have a slow learning curve when you mess with its air/fuel mixtures without telling it.

 

thanks for the info. i'll do it first thing tomorrow morning. let you know how it goes.

 

Any luck?

 

eureka! it was the MAS. i had it in backwards. i'm such a dumbass. anyway it's a wonderful improvement. instant torque. i love it.

 

Well, that's a new one. At any rate I'm glad it's running well now. Congrats on the new intake.
