EFHatchTuner Posted March 18, 2009 Share Posted March 18, 2009 Ok, so I fixed check engine light. A sensor on the block was wired backwards, Now the RPMs jump up and down. I thought it might be IAC but if I hold RPMs at 5k it jumps from 4 to 5. If I hold it at 6k it jumps from 5 to 6, etc. No matter what RPM its at it does it. One of the many reasons id rather not have OBDII. Anyone have a clue? Link to comment Share on other sites More sharing options...
Kastigir Posted March 18, 2009 Share Posted March 18, 2009 I believe that's a distributor problem. Someone can correct me if I'm wrong, but a jumping tach is one of the symptoms. Link to comment Share on other sites More sharing options...
lceah Posted March 18, 2009 Share Posted March 18, 2009 maybe it's a clutch problem... does this happen right when you start driving or after a while? If it's after a while, then it could be the clutch because of the heat of a while of driving... Also could be a number of other things: like having to clean MAF (Mass Airflow Sensor) or idle...I'm running out of ideas... Link to comment Share on other sites More sharing options...
EFHatchTuner Posted March 28, 2009 Author Share Posted March 28, 2009 It does it even in neutral. I put a new TPS on it, same thing. I havnt had a chance to drive the car yet. im tryin to get all the bugs worked out first. Link to comment Share on other sites More sharing options...
lceah Posted March 30, 2009 Share Posted March 30, 2009 Have you messed with the idle screw anytime during this whole thing? I just thought of this...have you reset your ECU? This is free to do and might work or not but doesn't hurt to try. To reset, take out the fuse for ECU, wait a few minutes, and then put back in... good instructions on reseting ecu: http://www.team-integra.net/sections/artic...sp?ArticleID=82 (your fuses could be different for your car so look at your diagram) Link to comment Share on other sites More sharing options...
