UM, ok here is what? it ends right after lol. all I see is the dash lights come on and thats it.

 

k more video

 

i think your IAC valve is bad. that will cause that wierd idle
























cause i can easily tell from that video

 

ok I took out the dsm 450's and put the stock 240's in...changed the bin in crome to a stock p06 because I dont have vtec hooked up yet...now look what I get... IT WON'T REV PAST 4000 IT IS BACKFIRING AND FLAME OUT THE DOWNLPIPE EVERY TIME I HIT 3900-4000 RPM THEN IT WONT REV PAST!!!!

 

Sounds a little like a WRX, annnnnnd we all have an idea what that means.


However, the problem just occured, correct? The motor was in and ran fine with a stock ecu, right? Then you threw in the 450s, the chipped ecu, and turbo gear and get that result, am I right? Basically, did the car function fine prior to all the upgrades then ALL OF A SUDDEN started acting goofy?

YES....it started to do this ---- when I converted to obd1 got the 450's in...and chipped the ECU!

 

sounds like a bad injector to me.
