Pudding

Hi all I'm after a bit of advice
I have a 95 impreza turbo and it has a missfire when it comes on to boost but only when the boost gets towards its max
I have changed plugs, leads and Air flow meter

I'm just wondering if any one else has any ideas?

take the rubber tips of the coil packs and check for cracks.
put a boost gauge on the car and check the boost pressure is not too high.

I have a boost gauge on the car it holds at just over 1 bar

Will check the coils at the weekend

while you are at it make sure the plugs are gapped at 0.65

I had a similar problem. Was an earth issue. Had to put the earth directly to the ECU to solve it.

Right I have checked coil packs all is ok and have checked the gap on the plugs that is fine to stefen1 how did you earth straight to your ecu?

when u checked the Coil packs did you look under the rubber or look at the rubber covers on the ends?
I have to agree with a failing coil pack.

Silicone grease into the boot of each coil pack. Improved the running of my 95 WRX wagon no end.
