What’s wrong with my car – Poor engine performance at low rpm after wiring repairs?
A while back I had trouble with my Ford Focus ZX-5 2004. It started miss-firing some cyclinders. Mechanic found corroded / damaged wires for ignition system. He patched them up and this fixed the problem for a couple of weeks, then it came back.
Went back he, and he was actually able to find a replacement wiring harness from Ford. He installed that.
Car is not miss-firing, but runs like CRAP... Going in reverse slow for example the car sputters and has to power unless I keep the Revs up. Same trying to drive around 100 km in 5th gear and trying to accelerate... no power.
The check engine light does not come on, but sometimes my transaxle transmission check light does.. at the same time sometimes the anti theft left goes nutty.
I don't want to bring the car back to same mechanic because I don't trust him anymore (also based on tires I bought which I really don't like).
Now maybe a new symptom since it got colder, the heater seems to blow cold air at low rpms.. rev the engine and I can get hot air.
He probably screwed up the wires again.. just trying to know if there is anything else obvious before going to a new mechanic.

Sounds like he has the wiring harness hooked up wrong, which is not good on electrical patrs and sensors in cars system either. should have a pro. check it out
