misfire question?

[MikeDombeck]

recently, i changed my knock sensor. but it still flashes 34 on the ecu after resetting it with the new sensor in it..... car runs 100% better in vaccume, but once the turbo spools, it misfires... any more ideas? its not a vaccume issue....

Head gasket or boost leak

[MikeDombeck]

i changed the ignitor, and tightened ALL of the intake system, im hoping it isnt a head gasket, so is there any other options, anyone have this happen to them? how did you fix it?

have you checked your spark plugs?

[MikeDombeck]

new plugs, new coils, adjusted timing, new ignitor, new knock sensor, cleaned MAF, redid vaccume lines, tightened battery terminals(if that matters), im thinking about having the car re-wired......
