ok so heres the deal, im in the process of buying a 89crx si. it has a d16z6 swap. i havent gone to see the car yet all i know of it is the pictures and talking to the owner who knows nothing about cars..awesome right? its a pretty clean car. he tells me it wont rev past 4000rpm and that it needs a new distributor and ecu and should run good. i already have both. is that what the engine needs ? the other odd thing is this "special" guy has just the air filter mounted directly to the throttle body, could it be a restriction of some type? im trying to look at all my possibilities before i go see the car this weekend this way i can hopefully get it to run right before i trade him vehicles.

 

It might possibly be the ecu if it already needs one.

 

the check engine light is on also..

 

air filter is fine, ecu is angry for some reason most likely its pissed about wiring, and its in safe mode

 

hmm,what would i have to do to get it out of safe mode? putting another ecu in wouldnt change anything then im assuming?
