UH-OH I'm in Trouble! AAN help advice needed!

[8valve]

Right guys, had an intermittent misfire which turned into a permanent misfire.

coil-pack, i thought...fitted a new one......still there.

ignition module....fitted...misfire still there.

checked all wiring for continuity etc, cleaned plugs, then replaced with new plugs.....still a misfire.

plugs are getting sooted up when she's run.......

she now won't take revs when you press the accelerator, and is running like a total pig, and blowing blue/white smoke under throttle load.

compression check showing 150psi in all cylinders...all this info is from my best mate who's also my mechanic....we're stumped!

HELP! please! Paul.

MAF or MAF connector, either that or you have a big air leak.

One thing it could be is the ref hose to the fuel pressure regulator, if this has split then it will be way to rich at idle because the pressure will be too high, this will soot the plugs up very quick.

You need to pull the codes from the ECU and see what it's saying, this will help diagnose what the cause is.

Hey Jo, thanks for the tips..no error codes showing on diagnostics....

Have you checked the coil pack boots for damage?

[8valve]

yea, they're all intact....
this has us driven nuts trying to trace it.....

Disconnect the MAF, check if it gets better.

Have you pulled (and replaced) the injectors, one by one, with the engine running at idle to determine which cylinder has dropped out? Once you know which cylinder, I would first check to see if that spark plug is tight and its coil to plug boot is in good condition. If the plug is tight, I would pull it and examine it. F5DP0Rs are starting to drop their electrodes.
