Ok so. When im driving all normal like. Like straight cruising the hood for biddies and what not. My car seems to be like, i dont know, stuttering maybe. It kind of feels like its bogging.

When I open it up, parkway driving, where im hitting 80 or more, it seems fine and smooth. I have no idea what this problem is. I put an engine cleaner in it the first time it started to do this and that seemed to clean it up about half way through the tank. Its happening again and im not going to keep pouring that **** in my engine.

Any ideas??

This happens in all gears. I changed my fuel filter recently, which I thought could have been some what of an issue since i havent changed it in four years..... im sorry guys.

Any ideas would be awesome. Thanks.

Is the ecu throwing any codes?

Sounds like dirty fuel try running a fuel system clener like (heet or deet not sure maybe even heat) this will actually get rid of the accumulated moisture in the bottom of your tank and it could also be a dirty or clogged fuel injector. Also might want to take your fuel filter and dump it into a clear jug to see what comes out, even if you dont see anyhting then i would replace it anyway. Check all your plugs for fowling. Check your timing.

If that doesnt do it then let us know and ill keep thinking as will some other's who would have mroe expierance then me on Z specific tech.

dont run heet, those alcohol based products shouldnt be ran through Z32's. also i doubt he just randomly got dirty fuel.

Fuel is brand new. I changed it when it first started happening.

I ran the sea foam fuel cleaner through it and I thought it had cleared it up.

The problem is intermittent.

I think one of my coil packs may or may not be shortening out.

I was thinking it was a possible misfire but wasnt really to certain about that untill my friend had said the same thing to me.

Then he did this thing and put his head up to my hood and said its misfiring in the left bank. Hes an idiot, but, is there a way I can check, ohms or whatev to see if one of these are shorting?

Let me know playas.

P.S. It clears up after 3500rpm, but under that it still has that bogging like feeling to it, it all gears.

You should really check ur ECU for codes...that will point you in a good direction (at least to start). But sounds like the classic symptoms of the MAF, if it is only around the 2k-3k rpms.

The classic symptoms are vacuum leaks.
