ok...finally got my LS in 98 EK swap goin...but after getting the correct ECU (pr4) and everything...it idles at 1,500 to 2,000 and doesnt really fall in R's quickly like normal...i looked at my fuel pressure gauge and its reading 55...just put in a new fuel filter and all...could it reading that high make it idle that high?? i know 55 is high too..i think i bought the car with aftermarket fuel pump...dude never said...cause he's a freakin idiot...

plus...i have a CEL...
i went to go check it and all..and it won't blink...car runs prefect..any ideas? except for the high idle anyway

a PR4 is an OBDO LS ECU.you need a P74 or P75 ECU.what jumper harness are you using?

dude.....i'm lost man....this ECU reads pr4 and everyone says its for obd0...but its pluggin into my obd2a to obd1 harness....i looked up a sheet on all the ECU's and they made the pr4 in 92 and 93 but i guess they were obd-0...this ECU doesn't have the blinkie light ethier...??? any ideas....its workin but i have a CEL...and i think its intake temp...which i'm sure is differnt on obd-0 cars right....

a.k.a still lookin for a dirty *** cheap ECU...cause i got this pr4 for 50 bucks..


let me know i guess...
