Car feeling sluggish.

[95Vert]

IDK what's wrong. It'll still get up and go if I floor it but I think I'm leaving some power on the table. Every time I shift, it feels like it has to get out of a hole instead of just keep running smoothly. While cruising, it'll kind of miss a bit. You can hear it in the exhaust. I already changed out the plugs, cap and rotor, o2 sensors, cleaned the maf, adjusted the tps and replaced the iac(just for kicks, under warranty) and it still does it. What else can I look at?

How old are your wires? Does it idle smooth?

 

[95Vert]

Yeah, the idle is pretty smooth. I have an extra set of stock wires in a box, I'll try that tonight. Besides that, anything else I should look at?

 

[TheDamned]

My wires are pretty old, I think they were never ever changed on my car.. Does wires makes that much of a difference ? And is paying extra pucks for a premium quality wires worth it ?

Thanks

 

[95Vert]

The discussion about wires has been brought up before. And the consensus was that they're not needed, you should be fine with stockers, but most of US do it for asthetics. They don't hurt performance, but they don't improve it either,IMHO.

Nacho, any codes?

The part throttle miss can be tricky to track down due to the variables involved.
A quick thing to do is clean your PIP (you live in a dust bowl like I do, from the sound of it). I cant keep the engine bay clean, including under the cap). At speed, the shudder-window edge might be studdering. It takes 20 seconds to clean it - worth a shot.

Nacho hit the nail on the head with the wires. I run Autolites on a couple cars (with DIS ignitions no less) and they do fine. On the stangs, I run Mallory Sidewinders and MSD SC's (for machismo and looks).

Good luck to both of ya.

Nope hissin, no codes cause I haven't checked lately. I checked about 2 months ago but at the time, it wasn't doing it. And yes, I do live in a dust bowl. I thought I read somewhere that I have to remove the distributor to clean the PIP, is this true? If not, where in the world is the pip and how do I clean it. BTW, this problem began about 2 weeks ago. I suddenly started, that's why I switched out the above mentioned.

PS. DAMN!!!!!!!!! On your post count Hissin, is that for real?!?!?!

I have no idea what that means.

The post count is real - you guys know how often I'm on here.

Nacho, the PIP is inside that plastic bowl under the cap. If you remove the cap, you'll see the components toward the outer circumference of the bowl (brown and black plastic parts, as I recall).

You do have to remove the dizzy to replace the PIP - that might what you're thinkin of. Just to clean it, I remove the cap and rotor and spray electrical contact cleaner in there - dont use a whole ton or spray real forcefully - just enough to clean things up).

Good luck.

Thanks Hissin, and congrats on the count.

 

[95Vert]

I can use carb cleaner right?

 

[OrangeMustangGt]

use rubbing alcohol or electrical cleaner... preferably on the end of a q-tip like your cleaning your maf!

 

[95Vert]

I didn't get to do it last night, but tonight is for sure. I have rubbing alcohol and q-tips, so I won't have to spend any money.

I figured it was something goofy like that - I read the goofball sub-forum (The Outhouse or whatever the Name de jour is) and see you guys using the funny talk. I always felt left out since it's like listening to the Trekkies speak Klingon (sp?).

It took me 13000 posts to get an avatar and about 15K to post pics, so a hacker I am not.
