it acts the same with or without the temp sensor connected, and the coolant temp sensor was replaced.

Test timing when it's hot?? if it is possible to do I should be able to do it. I have new plug wires to put on this weekend, don't think that's the prob. I'm about ready to take it to the shop. It's crazy that something somewhere is sending a code to the ECU to retard the timing or something to cause it to run bad

OK, replaced the AFM, TPS, ECU and the coils, no change. However the car was up to temp when I swapped the ECU and it ran perfect for a few minutes then right back to normal as in running poor. Any other thoughts ?

Would the Thermostat cause this ? I'm looking into the coils now, If I raise the RPM's very slowly it will almost run fine, but when you try to accelerate fast it stumbles, coughs and shakes. Strange thing is often when I raise the RPM.s over 3000 it will clean up and run well... although this can even be irregular.

Still running poorly after it warms up. The thing runs great for the first 3-5 minutes, then it tanks. Almost like it's choking out or starving for fuel. Any ideas.
1991 318is 98K , No codes,already replaced, 02 Sensor, fuel filter, Crank sensor, Cam sensor, Coolant temp sensor, checked fuel pressure, cleaned intake and injectors, new plugs, cleaned up the Vacuum hose mess under the manifold, cleaned air filter, compression test was good, prayed and lit a candle several nights in a row.. Thanks for any help.

Would the Fuel Pressure Regulator only act up after the engine is up to temp? thanks

Hey Guys, need some help. 91 318is, 98K, Runs fantastic until it warms up and then it runs bad on acceleration. Already replaced the 02 sensor, fuel filter, plugs, did the under intake drill to cover all the vac hoses. Ran the stomp test, no codes, tested & cleaned injectors, cleaned intake ports. Still no improvement. Anyone have any ideas, BTW, thanks for any help.

I didn't remove the throttle body, was I suppose to ? Also, chasing the poor running condition. It runs fine cold it's after it comes up to temp it starts to stumble when you gas it. At low RPM's its all good. When you punch it, it acts like it's almost flooding out and the car seems to vibrate a bit ? The stop test show a 1223 code thanks

Ran the Stomp test and I think it's telling me 1223, however it continues to repeat this over and over and over without stopping ?? is that normal. Also some have told me that the 02 sensor may be bad. I disconnected it and ran the car for a few minutes, re connected it and did the Stomp test drill again, it still only gave me the 1223 code any thoughts, thanks
