just picked up a std hatch with a ls in it pr4 ecu and new dizzy both tested good. wont rev past 26-2800rpm. checked wiring and everything and cant figure this thing out. wiring is kinda sketch. cant check cel's with this ecu for some reason.... any ideas. car has done this since swapped.

 

Have you checked your plugs

 

plugs good. runs like a champ until 2800 lol have kinda a rough idle aswell

 

check ur ecu, it might be the obd1 pr4..i remember when i was tryin to convert to obd1 my car would rev past 3k rpm because the incompatibility of an obd1 ecu wit and obd0 dizzy..and make sure that ur engine harness is completely converted over from dpfi to mpfi..
