Ok here's the deal replaced coil packs & wires,putting wires on and I think fire order is 1-8-4-3-6-5-7-2, my problem is coil pack 5/8 or 8/5 was replaced and has no numbers to go off of. What's the wright number 5/8 or 8/5? If someone has diagram of firing order, just to safe before I put it all together.

Thanks Tom

Thanks everyone for all the valuable info,I'm sure I'll find the culprit by weeks end. Just out of curiosity if it or was bad gas how long would it take for new fuel to kick in? Drove till 3 bars above reserve and filled it up( premium).

Exhaust smells like someone lit off fireworks,if that helps any.

Tom,

Have you pulled the plenum yet?

Can you verify all injectors have been changed?

Don't worry about the DIS yet. When I posted that last-night I was thinking about another thread, and posted on yours. My apologies!

Did you check for spark tracking on the plugs?

The kicker is the fact this started all of a sudden.......
Did anyone mention the MAP connection yet?

Manifold Absolute Pressure Sensor (MAP)

MAP Sensor Hose Fix TIPS
MAP sensor hose disconnected

x2 on the DIS for later.

No haven't pulled plenum,no tracking on plugs,injectors have been changed. I'm leaning towards coil,will do test with timming light test on wires & pull plug and check spark color. But before that will check fuel pressure,will keep you posted

[TomZR1]

Ok did a fuel pressure test full throttle 49-50,I assume that's good. Next I'm going to remove plenum and test coil pck

[TomZR1]

Never mind figured it out, overall it was pretty easy to take off so while I was taking off the coil packs I noticed the plate the coil pack sit on the plug was off in the back so I'm wondering if that was the issue. If I use an ohm reader can I see if the coil packs are bad? And what's the reading for the ohm on the coil packs?

[Z06scentair]

Not sure on the coils...since your there replace them, It will cost about $200.

Clean the oil debris and tighten the pcv housing cover.

[TomZR1]

There's a lot of oil down there, will be replacing with Borg Warner.I think my problem was a disconnected wire clip where coils sit
