Hi guys.
Back again with an annoying off idle stumble. Car wants to stall, has no power then like a switch is thrown It up and goes like a cut snake.
Here's what I've done.
New o2 sensors.
New coils.
New fuel filter.
New leads.
New spark plugs.
Cleaned the throttle body
cleaned the fuel tank and fuel pump sock. (wasn't that grotty at all).
When it plays up it spits and farts and feels like it wants to die in the arse, then I'll get a back fire off one bank (has happend on both banks) and off it goes like there's nothing wrong.
All thats been done recently is I fit up a whole new exhaust system. New cats, new Extractors and 2.5" twin system.
There are no codes showing on the scan tool. The fuel trims seem fine. The ignition advance is fine. The TPS and IAT is fine.
It almost feels like a car with a carby that's too big. Anyone that's been there knows what I mean.
The old boy took it for a run and said it feels like the idle is too low. Which makes no sense obviously.
But could the TPS or idle control be up the ****?
