Running Rough - No Codes

All of a sudden the SVX has started running rough. I was out this morning and it was fine, but when I started it to go back home, it felt like it wanted to stall at idle. It didn't actually stall on the way home, but the RPMs bounced around whenever it was idle and it feels a bit sluggish. There are no codes. The plug are about a year old and the o2 sensors are new. It has also recently had injector cleaner in the last tank of fuel. I am wondering if I had a coil pack go bad? Would that give a code?

Re: Running Rough - No Codes

Welcome to the club

If you want help swapping out coil packs, I think I have one or two spares lying around. I'm very familiar with the area

I'd check plugs first and go from there. My mom's 39k mile Impala magically got a carbon tracked plug so maybe you did too.

Actually if you have some time, I'd like to have you take a listen to it and let me know what you think before I start swapping parts [or before I bring it to the local shop]. If you think it may be coil related then yeah I'd like to swap a few. Could be a vacuum leak too I guess. Would a PCV valve could roughness?? Not sure the last time that was changed.

I have plenty of time these days. Not having a job does that to you .

You name the time and we can do it. Supposed to be nice a few days this week. Next Saturday is out for me though.

Re: Running Rough - No Codes

Manarius came by today to help me, after we pulled the wires from the injectors we found that the passenger side front cylinder was not firing. We changed out the coil and luckily that took care of it. (Pending some more road testing)

Thanks Jason!
