95 neon fan problems

[irish30]

Pulled codes out for coolant sensor signal out of range, replaced the sensor, no change, fans come on for a couple seconds, engine almost stalls, and fans go back off. unplug the sensor which would represent a cold engine, no change, A/c is unplgged and relay out, unplugged the fans and the engine still sputters the same as if the fans were trying to run, PCM??????

How's the coolant level? When was the last time it was replaced or flushed?

[irish30]

Coolant is full, clean and tests to -35C

Can anyone tell me the deal with spark plugs on these cars, what difference do old ones and new ones make on engine strategies, I have been told that the cure for this neon is plugs, I can't see how this will affect the fan operation but nothing is for sure but death and taxes.

Champion spark plugs every 10,000 miles have been proven best for the neon, but should in no way affect fan performance.

Thanks, replaced plugs no change in running problem, I will be tracing wiring to find cause, It has to be wiring or internal P.C.M. fualt based on driveabilty problem, if you here or know anything else let me know

Replaced plugs, no change in fan operation, two codes, on for ECT (22) and on for IAT sensor (23) has anyone had or found specific areas for wiring concerns on these engines? Has high mileage 245,000 kms.
