WHat Does This Look Like?

Post by 69 1/2 Six Pack Bee »

I have been having an issue now with trying to run the engine. Man, if it's not one thing it's another :(

Look at the snapshot of the log and see what you think. If I start to give it throttle (as indicated by a constant 17 on the TPS graph) the engine pops and sputters and runs really rough. If you look at the "engine" graph it was going from a run bit of 9 to an off bit of zero (is this right?) and the rest of the functions pretty well reflect this. Then, all of a sudden, it will straighten up and run fine. Remember, this engine was running just fine with the MS-I and now with the advent of the MS-II all of my problems have arisen.

Would the 8-pin module cause this or is this an issue where the entire 12V line to the MS-II is getting interrupted? If I let off the throttle then it would idle fine but if I depressed the pedal it would act up again.

It has done this a couple of times now and for no apparent reason.


Thanx,
Bud MS-II/V2.2/MT2.25
