i got a pr4 for my integra...its a 96 rs witha b20b in it...i was told the pr4 was obd1 and i have an obd2 to obd1 jumper harness...it connects and works..but the idle is really crappy...it idles at 500 rpms...and if i give it gas and let go...the idle drops to 100 rpms...and comes back up...it dropped so low once that it shut off and wouldnt turn back on unless i cranked it with my foot on the gas pedal...PLEASE HELP

 

wow...no one? cmon guys...

 

adjust the idle??

 

my friend messed with it...but he just kept movin it around...wat way should i adjust it?

 

its the little flat head screw lookin thing on the tb right?

 

take it to someone who knows what their doing with the car ( dealership ). Sure you may pay a bit but hopefully they'll fix it. You can have em only diagnose and troubleshoot for an hour. Might as well have em fix it instead of a friend "movin it around " and probably making things worse.

are u sure that's the right ecu u want to run

 

took the pr4 back..got a p75...and the idle is weird until it warms up and runs perfect

 

the p75 is also for an auto...so i dunno if thast why the idle is kinda weird..but not as bad as the pr4

 

I had the same problem actually, but it was the ECU.

 

is the throttle cable too loose?
