Arrow PO102 code advise

mass air flow sensor..... could it be anything else?

cleaned the MAFS with CRC cleaner, looked clean to begin with.

would any thing else cause this code?

the idle is jumping a grand above normal then dropping and stalling engine, at stop lights and while driving down the road. the tack is all over up and down.


Thanks~

Unplug the MAF and see if the car runs a bit better. You can drive without it as long as your easy on the throttle. No more then half throttle.

should add that this starts acting up only after the engine has reached normal operating temp.

I will unplug the sensor on the way to work tomorrow

I did unplug the sensor and drive, it ran perfect.
stopped by auto zone for a 2nd scan it showed that same code 3 times. yesterday at advanced auto there scanner showed the code one time, dont know if that is telling me anything.

sure wish we scanned cars at Carquest as I mix/tint paint there...

If you unplugged it, and it ran perfect, then I think you have narrowed down the suspect to one item. Obviously the MAF, right?
