alex37211 Posted July 22, 2009 Share Posted July 22, 2009 do you have the correct ecu and/or jumper harness? You are running an obd2 engine in an obd1 car. Which ecu are you using? Link to comment Share on other sites More sharing options...
preludefreak1080 Posted July 22, 2009 Author Share Posted July 22, 2009 i know its the right ecu because it ran fine when i got it and for a month after that then after that month it just stopped starting i fixed the starting problem with a coil and a starter just now runs like crap Link to comment Share on other sites More sharing options...

xxhrdcr4lifexx Posted July 23, 2009 Share Posted July 23, 2009 you prob just knocked off a vacuum line and or didnt put 1 back on in the right spot, I did that 1ce b4 and my car ran like death and a really low idle like around 150-200 and it smoked alot like i had some burnt up piston rings. It would also bog down bkuz it wasnt getting the right fuel air mixture bkuz of that line being in the wrong place. so i would check your f/i vacuums and make sure there all going to the right location and not guessing where they go...

shanehonda Posted July 24, 2009 Share Posted July 24, 2009 check your aic and your tps could be that too they control your idle and everythind if they are bad or broken your car will run like crap they are on your manifold the one is on the front bolted on the your intake manifold, and has two coolant hoses going to it. The other is located on your throttle body check that my buddies b16 bogged down to like nothing and it did die once, so check it out man Link to comment Share on other sites More sharing options...
