I have read the thread talking about a small flat spot and I have a similar problem but on a larger scale!
When the engine is under any kind of load the car flat spots like crazy! The first thing i tried was to change the plugs but that did not work, so the next thing for me to do is check the coil packs...
I was wondering about the best way the single out faulty ones in the set? Or if any body else has any idea as to what this might be!
NOTE: I dont think it is the fuel maps ( Flats spots a way to big)
& I dont think it is the cam timming ( had someone have a look at it)
Any comments would be helpfull, thanks guys....
