Seasons Greetings to the club. O K down to business. I just installed a PCM from intense. I was successful with the security relearn procedure but now the car will only run for a few minutes before stalling. It seems as though the SC dump valve is opening without giving it any gas. I am able to hear loud air sucking without opening the throttle at all. HELP!

The dump valve should be open at idle.

The hissing cold idle IAC is normal for the first few minutes until the car warms up a bit.

Doesn't explain why it's stalling. Any codes?

The sucking air noise seems to only be when I am at WOT usually. It is definately not the right sound while at idle. Could this be the case learn . First there was no code ,no check engine light. After I goosed the throtle a little the light came on. I then disconected the battery cabel to clear the light.It worked but the car idled no better?

Yup, sounds like you need a case learn.

Clearing a code isn't going to fix a car, you need to get the code.

A case learn should be done anytime an engine OR pcm is replaced. If the pcm is just reprogrammed, it shouldn't need a case learn.

If it is not the original PCM, it will need a case learn. Did you use the original PCM or buy one from Intense pre-programmed?

Thanks for the replies. I e mailed intense so I can return it for another. I put my original PCM back in and it runs fine ,no codes. I just dont think that a case learn would fix the problem. The car starts chugging like a train locamotive. After that it stalls or I have to floor the gas to keep it going. Then the service engine light comes on but doesnt with my PCM. Thanks again I will let you guys know what ends up happening.

Just talked to John from Intense. Way cool! Their going to send me a new PCM out today. Just thought Id let you guys know. John said if it was a case learn it would run very bad and be hard to start. Its easy to start and idles smoothly untile it starts its train impersonation. Thanks again !
