So on Thursday I finally got round to replacing my battery on my '96 Fiesta 1.25 Zetec, and ever since then the car has has some serious power lossage problems, I seem to remember I had the same thing last year after a cambelt change, something which also means disconnection of the battery. I had the old battery off for a while so I could clean all underneath it ETC, I think this could have lead to the ECU being reset?
The car tends to struggle to move in first gear when it's cold, then it will burst into life and jolt forward, it was also struggling to get up an incline on the M5, normally even my 1.25 can do over 80, but it was doing 60 and slowing down, had to change into 4th. Is this something that will just go like it did before, or is there something I can do about it.
