These are not aftermarket computers. They are different abbreviations for the car computer

yeah roger got that... i understand... it just has the eec iv that it is supposed to have... i think i just removed all the stuff in front of it for the first time... it has definately never seen human hands... so no it is still just the EEC 4 computer that comes stock in it

I use a generic diagnostic card in a PGM tester and I can read my codes even though I have a chip. Just FYI.

I agree with Lee, check all grounds and connections(fuse box, etc). It may help to have a wiring diagram that shows all the connection of the diagnostic line from the ecu to the diagnostic port.

i checked the direct coneections to the comuter, and already checked all the fuses... i am planning on checking the wiring on the daig connector...ive been fighting this for a month... if the EGR valve electronic transducer was stuckhalf open that might create a big big problem... and even cause the free air leak... and also send the computer into convulsions... couldnt it?

Its possible.

Sounds to me like your losing fuel somewhere. Possibly someting that is not sealing well when it's cold; maybe your regulator is doing some weird stuff. Have you checked your fuel pressure?

Do you have the stock fuel pump? If not, how long ago did you put the aftermarket one in? I had a very similar problem that ended up being a loose clamp on the output port of the fuel pump that allowed blow-by and, in turn, a starvation of the fuel lines.

True, but there is still something strange if a scanner will not 'connect' to his computer

i havent checked the fuel pressure... because it didnt enter my mind that fuel might be a problem until my buddy asked me if i had replaced the fuel filter... which would be an obvious problem... but the fuel seems fine.. because it runs rich as hell... you can tell by the smell if nothing else... but neveretheless i am gonna replace the filter... and i still have all stock fuel components... you gotta draw down the vacuum to check the regulator pressure dont you?

QWKSNKE · 05-17-2005, 08:22 PM

unhook the vacuum line on the regulator and hook a fuel press gauge on the port that is around the fuel rail somewhere

jwillburn119 · 05-17-2005, 08:24 PM

yeah... that is way off... the guy that i bought it from drove it in SCCA and claims he won races... the suspension is more than adequate to do it also... and the body parts show track wear... but he said he never abused it... right... but it was a stock race, he showed me the " entrance prerequisites" and they provide for stock comuter... maybe he was just getting the idiot light to stay off... for the smog pump... but when i DSCN the wiring harness the idiont check engine light came on...
