2005 Ford Escape new computer ? Or not ?
2005 Escape Limited V6.. approx. 145k. Rough idle at first with "check emission system" computer warning. Diagnosis , Number 2 cylinder not operating. Bogs above 4000 rpm. Now tech says computer in car is gone. Needs repair. Help ! Car not in US and parts hard to get . Any advice would be appreciated. Already replaced plugs, wires, air filter, fuel filter, oil change.
The 2005 Escape does not use plug wires but uses Coil on Plugs. I suspect Coil #2 was bad, so you or a mechanic replaced it, or all of them? If it bogs, have them look at the Cataytic convertors. This is a common issue with these vehicles. If you drove for an extended amount of time with the CEL light on with a misfire, unburt fuel being sent to the exhaust, damaging the convertors, clogging them causing a bogging issue. Look at this before replacing a PCM, which rarely go bad.
Thanks Tom... when you say check the convertor. Can you tell if it's bad without replacing it ? We did plugs, fuel filter, air filter , oil change first. But no improvement. Would love it to be only the convertor. I would say the CEL light has been on and off for a 6 month period. Never constant. Does this sound like the problem ? During that time only misfiring at about 4,000 rpm. Then suddenly all the time.
