It has a slight hesitation at lower rpm's in park if I give it a quick tap up to 1.5k. It'll rev up fine otherwise. It has lack of power and a misfire while under moderate/heavy throttle (Def worse then it's been). More pronounced during shift's. I havn't thrown any codes in the 2 week's it's been happening.

Coppers have about 10k on em.

Sorry if i'm all over the place, it's been a long day and everything has hit the fan since I got off work.
 
I was thinking those or the copper's. I have a set of used cop's I kept as spares I could try. Guess it might be time to switch one by one. Really wish it would throw a code though.

The only other time my car acted like this it threw a code pretty quickly, which is making me come to conclusion's that it was something else(worse).
 
Unless one of the 764's is fowled, they should be good for 20K to 30K easily. Try the COP swap and I believe that issue will be eliminated and fixed. MAF may need to be cleaned also but it sounds more like a spark issue.
 
I clean the maf a couple times a year so that shouldn't be an issue.

And thank's :)
 
Nope, but my buddy that is doing my adap gasket sunday does.
 
I know, I just tend to think the worst sometimes. Not having the cel pop up after 2 week's of random misfiring triggered said fear. As I said earlier, this car has only had 1 issue with a cop going out and it threw a code relatively quickly.

Once he determains which coil is bad I'll replace it with one of my spares. I'm going to pick up a boot kit and plat's in a couple week's. Something that should've been done year's ago.

the LS's do this all the freaking time. most of the time without a CEL at all. the first time, our's gave us a CEL after about a week and made it easy to fix.
this time it's missing something awful. worse than last time. and there is no CEL to be found.
 
SB, those darn coils don't always set a CEL. I had one that was pretty bad especially under load in overdrive when the converter locked. I switched them out one by one and found the culprit (the last phuking one lol)

An easier quicker way is to get an ohmeter and test them all out and find out which one is out of range. You'll save yourself a bit of time and gas that way. ;)
 
Same with my mustang I had a misfiring coil and no cel. They won't always trigger it you just have to put it on a scanner and see how all 8 are firing.
