coil packs, or just a boost leak, or clean out the boost solenoid next to the air filter.

changed... not cleaned.. 99% of misfire on boost on an early car is down to coilpack problems they last arounf 4~5years or 80~100k miles

you have to remove them to change the plugs

lol he's changed plugs and leads and doesn't understand that it does have coil pack and not leads .so i would surrgest ya go back to your engine bay and look again .and once ya seen that there is no leads then look and see that the plugs havent been changed as ya would know where and what a coil pack is .

maf is in the black tubing after the air filter box .

and the boost solenoid i would leave alone for now as ya seem a little confused at the moment
