help please
so im having some real trouble with my 99 integra gsr now whats happening is like a hiccup the car will be fine then the rpm will just drop 500 rpm and the car will suck in a lot of air now the mbars will go up 200 and i have changed the ecu, tps,spark plugs,and wires,cleaned the distributor, and cleaned the iacv(intake air control valve) now i have noticed when it hiccups that the green light on the demon will flicker and i was wondering if maybe the demon is bad or if it could be anything else.

I looked at your datalog... Very strange to see only the TPS wigg out.... and the fuel goes up accordingly based upon TPS... The other sensors (IAT, ECT, Etc) don't wig out like that... Very strange... Do you hear the main relay click when this happens?

We have a similar issue with a customer car, tps bounces around a lot, fuel value sky rockets randomly, gos pig rich, then comes back to normal, high load doesn't seem to be effected from what I remember.

if post fuel is enableing and your ARE getting a ECU reset then you most likely have a RF issue. Some things that can cause this are MSD ignitions, MSD or some of those aftermarket jumbo plug wires, non-resistor plugs make it worse but usually with a good set of wires this won't happen. This is most common on OBD0 vehicles but not exclusive to. Then you have all your other basic reasons like main relay, bad grounds, bad socket in the ECU, loose ECU connectors etc etc.

Yea that non digital msd stuff is junk, I fight with customers all the time over them and have seen ignition issues disappear time and time again just switching it back to an oem dizzy.
