Evening all, a few days ago i posted up i was having a few issues with the 3dr. She'd suddenly started to missfire when coming on boost.
Since then i've done the following:
Changed fuel pump
Changed Fuel filter
Confirmed good Voltage at pump
Changed fuel pressure reg
Changed Map sensor
Changed Phase sensor
Changed Plugs
Changed Crank sensor
Changed Water coolant sensor
Checked dizzy cap and rotor arm (both look in good nic)
All sensors/plugs etc gapped correctly (using info off this site)
And STILL it missfires at me!! I'm not 100% but i think its overfueling when it does too, as when it first started to miss i checked the plugs and they showed a good burn, since i've been trying to solve the problem and test driving the car down the road and back its coaked the plugs up black now??
Whats left to look at, could a HT lead give issues only coming onto boost? One of my leads is "suspect" as it looks a little "rough" Car drives fine off boost, i know the spark increases on boost doesnt it?
Maybe ingnition amp also?? Am clutching at straws at the moment to be honest
Anyone got any ideas? Spent a fortune so far and got nowhere!
