^^^ true true i wonder what would have messed up the ECU :/

[einstein57]

They just go bad sometimes. Could be from something as simple as a voltage drop. I fried one starting a car with a low battery from not driving it for a couple months. Ran similar to not having a good cps. Swaped the ecu just to elimate that as a cause before I got my hands dirty and it ran perfect. Sometimes the circuit board just gets some surface corrosion and can be fixed by cleaning them up with a toothbrush and some denatured alcohol. Sometimes.

ill pull mine out tomorrow after class and see if i notice anything on the board. it ran pretty good today but meybe it was a fluke... lol

Are your gauges working properly?
If you have a bad connection at one of the DME plugs, the intermittent info drives the DME nuts. You get bucking, surging and big pops out of the tail pipe.
In my case, the water temp gauge would go nuts as the surging started.

the water temp goes nuts on any E30 lol and nah its fine when it decides to miss. but this is the 2nd day its been good.! hopefully it stays that way.

Not when the solder joints are intact.

Did you find a problem yet or did magic fix the car?

nope havnt found it yet. didnt get to pull my ECU yesterday we were to busy at the shop...

Kick your car down into dumb mode.

pull the Cam sensor plug.

Start diagnosing from there.

There will be no adaptation and no vanos.

You have a metering problem (or at least it sounds like it) Since its fine full throttle and not part throttle you will need to work within your open loop / closed loop parameters.

well its no longer find at full throttle i changed the one stuck injector and it cleared up a lot i was thinking about putting all my good green tops in for now.
