ECU Problems? Help!
Discussion
Can anyone help with this problem that reared its head yesterday?
When driving, particularly under loads such as accelerating hard or going up a steep hill, the engine begins to surge violently, lurching the whole car. The car misfires and lurches, and there appears to be no power available, and then suddenly the problem clears and she takes off like concorde. 10 minutes or so later it starts all over again. When you have the roof down, I think you could smell unburnt fuel coming from the exhaust. At first the problem appeared to clear if I pulled over and revved the motor a bit, but I'm not sure if this was doing anything. Once the engine gets spooled up to a 3-4 thousand revs, she's off but as soon as you change gear its back again.
I thought it may be the Throttle Position sensor, but a mate told me that I could disconnect it and smooth, although less rapid progress, would resume. Disconnection of the TP sensor in fact made the problem much worse so it can't be that.
The lurches became so violent and unpredictable that I eventually gave up and called the RAC. (PS. Don't bother with that useless bunch either: Took them 3.5 hours to turn up with the right truck- driver told me Brittania are better and they get first priority on contractor call outs!)
