Wasn't sure where to put this exatly, but, yesterday some friends and I put some coilovers, rotors, pads, etc on my 99 Eclipse. I took the car out of storage yesterday and replaced the battery because the previous was dead.
Anyway, sometiems when I am driving my car now, and apply the brakes, the 'Check Engine' light comes on and the electronics of the car hesitate. Like, I will see the tach needle drop as if the car was turned off though the engine is still running... the radio blips off then on and so forth. All this in about half a second.
It does this whenever I put a lot of 'load' on the electronics of the car... like after we were done yesterday I turned on the heater, lights on, rear window defrost, radio, and the car felt like it was going to stall out. Idles at like 500 rpm (on my safc). Drove it home yesterday with no problems... then today is when the 'Check Engine' light would come on whenever I applied the brakes and the electronics would go haywire for half second or so. And, this only happened like 1/3 the time.
I was on the freeway today and turned on my lights and it did that again. It's like the car is shut off/ turned on real quick. I don't know...
I drove around a little a while ago and didn't have any problems.
The only thing I can think of is because the battery was replace, the ECU had to reprogram itself or something??
Installed suspension and brakes on my 99 and having weird problem...
