ok, spent a bit of time on it this weekend
new plugs .8 gap, valley cleaned out.
coils have been siliconed, contact cleaned all plugs and ignitor module
Cleaned afm/plug and tps/plug
Its a terrible miss but ONLY on WOT. The car idles fine, and drives fine..its only when i floor it gets around 4000rpm does the car farts and pops, dumps some fuel smoke etc. It doesn't seem like a coilpack miss or the sort, more like a failing sensor of some sort?
What else should i try?
