Help!! still running like dirt.

[beemrmem3]

Ok, so i had a pretty bad exhaust leak. My car was running like shat. So i fixed that, cleaned my MAF. Reset the ECU(removed - battery terminal) And its still running like junk.

It idles really rough when the engines cold and warmed up. It stays at about the same RPM 600-700 but shakes the whole car when it idles. When i rev it. It sounds like its running on 6 cylinders. When i drive it around it bucks and stumbles all over itself. After i drive it for about 15 minutes its seems to get a little better. Not missing as much, but still does. It seems like its getting worse. Almost to the point were i cant drive it. Its almost as if its getting to much or not enough fuel. Maybe something with the spark??? I did plugs, wires, cap and blaster coil not to long ago.....

i cant figure this one out....help

how bad was the exhaust leak? and where was it...

 

[beemrmem3]

It was where the header meets up with the H-pipe. It was pretty bad one of the bolts came off. Loud!

Check the wires maybe some came loose.

 

[beemrmem3]

Checked those today as well. ARRG

 

[NYSTANG]

considering where the exhaust leak was maybe an exhaust valve went? no back pressure is not good for exhaust valves. I would double check your igntion wires first tho. If you have a compression guage I would do a manual compression check. If you dont have one I'm sure autozone would have one for cheap. It would be worth it. Best of luck

I was just dealing with some bucking, studdering, and backfiring issues and in the end all it was was my spark plugwires were on the wrong cylinders.

But it did fix all my problems with the bucking. It is worth a try.

I dont think its the wire placement. Cause i havent messed with the wires. Its not the exhaust valves cause it only bucks most of the time. Not all of the time.

make sure your timing hasnt wandered to a higher number. have had that happen a few times. whats the most recent thing you remember doing before all of this was happening or has it been doing it for that long??

 

[beemrmem3]

I didnt do anything before it started happening.
I have got a CE light a few times. So im going to try and check the code today.

 

[beemrmem3]

Well i ran the codes

I got a 212 in memory ignition module circuit failure/spout circuit grounded. What is the ignition module.

In KOER i got
311 AIR system inoperative during KOER (Bank number 1 with dual heated oxygen sensors)

and

314 AIR system inoperative during KOER (Bank number 2 with dual heated oxygen sensors)

I dont know what this means.
