McDave Posted July 12, 2008 Share Posted July 12, 2008 One more thought. If your spark plugs have screw on tips, make sure they're tight. Will cause hard to find misfires. Link to comment Share on other sites More sharing options...

If you're plugs have screw on tips......... Remove those Bosch pieces of crap and put some proper NGKs in there Link to comment Share on other sites More sharing options...
RMVR53 Posted July 13, 2008 Author Share Posted July 13, 2008 ok...its all gone to hell now.... as posted above, ran fine with the TPS unplugged. replaced the TPS and same problem existed. Only other thing in the TPS circuit (other then the ECU) is the coolant temp sensor. Replaced that this morning. Now it won't even idle once it warms up and spits/carrys on just after warm up just sitting here. The only other thing I can think of that has been disturbed during this whole process is the harness itself. Possibility? IF so, then what other cars can I drop this engine in as I through with it...

Turbone Posted July 13, 2008 Share Posted July 13, 2008 Its definitely sounding more like a harness problem now. I had a problem something like this when I was swapping engines in/out a few times on my RX. The 2 big plugs that connect the main harness to the manifold and engine were not tight, making for a poor connection. Link to comment Share on other sites More sharing options...

I considered them, went back out and sprayed with contact cleaner and re-fitted. Also, as McDave suggested, I removed the yellow/white plug for the tach at the coil...no tach and still did it...and checked plug tips...but thanks for the suggestions. I guess I'll start reading the fsm to find which wires I'm looking for unless someone can point me to the culprits to check first... Bill Link to comment Share on other sites More sharing options...
