Misfiring like hell.

[Taheen]

Awesome!

Halfway home from Home Depot today the car was acting just fine and dandy. Then I felt a misfire going about 40 in 4th gear at light throttle. Just a little hesitation, odd.

A bit down the road I give her some more gas and she dropped. Just running like a dog. Missfiring like mad, no power. Lots of backfiring as I cruise lightly home.

I will get more details and a video tommorow. :( Did the ghetto test on the coils when I got home. Put a spare plug&wire on one terminal of a coil, grounded the plug and had somebody turn it over. Did it for each cyl of the coils. All gave an obvious spark. Not really a great test I know but still it was a quick something to do.

:( Really bummed.

SES or no? If yes, get it scanned. If no, idk. Possibly a clogged cat, bad plugs, bad wires, bad ICM, etc. There's so many possibilities for misfires.

No SES yet unfortunately. Sucks. Monday I have a day to myself, going to get it scanned just in case, new plugs and wires again. After that, hopefully even if it wasn't a fouled plug I will be able to at least tell which cyl is dead... really feels like she's not running on all.

The fun begins. :(

bad coils

Re: Misfiring like hell.

Scanned today, cyl 5 misfire. So replaced the plug and went for a drive. It is better, but still missing bad. Will replace rest of plugs tommorow and swap the #5 plug for an old one I have.

Ok, replaced plug and also went back with a new wire. I was getting a #5 misfire code. Here is the spark plug if it helps:




Starting to wonder if my old tired fuel pump may be to blame too.

Re: Misfiring like hell.

how are your wires? did you burn one? you could have the smallest crack that could give you those problems

Re: Misfiring like hell.

:) Thanks for the tips. I changed plugs/wires.. still bad :(

This was after I scanned and got only one code... #5 cyl misfire. Well today I scanned again after everything was deleted and I got the same code again.

Went ahead and replaced all the coils.. She hasn't run this good since I got her. :)

So happy now. :)
