Default Strange miss-fire

I am not 100% sure that the following was the cause, but seem to be timed well.

I went through a puddle... a big one... (thank you Ike)


Now the car for the last several days has stumbled albeit only during idle to half throttle. Anything above that, the car will suddenly "wake up" and take off. I had an SES light after the puddle incident, but went out before I had the chance to scan it.

My mods are listed in my signature but will also add that I have programmed out all of the emissions, skip shift, and the reverse solenoid is disconnected in case that might be pertinent.

PS... the SES light was a steady light (not flashing).

Generally anything part throttle is controlled by your front O2 sensors, MAF, IAT, and coolant temps. I'd check the O2's first to see if the heater didn't short out, more then likely they need replaced since they are the lowest sensor on your car that I listed.

Good luck
