another wot issue with a twist.

**Toms04compg** · 03-21-2012

So about two weeks ago i was driving normal and my dic tripped of the " reduce engine power " prior no leaks idle fine wot seemed fine also as i only bought the car a month ago so im still getting aqquanted. When the sensor went off it was a nasty noise while i stopped immediatly due to sensor. That sensor and or sound was never to be heard again but nowdays im getting so?e nasty hesitating under wot half throttle is ok ... No miss of any sort and my idle is also fine. This vehicle is stock. Autozone said they found a p0300 code but i have no lights on anymore after some seafoam that was three weeks ago. Clogged cat do this?

**Swiggles** · 03-21-2012

p0300 is a random misfire code. it wont set the light off the first time. you might need some new spark plugs, the supercharged cars like copper plugs best. a clogged cat could do this, put your hand at the tail pipe, if its puffing out steady then your good, if its puffing like a pulse then you have a clogged cat. i would start with the plugs first tho.

also how many miles on it and are there any mods to it.

Bump

x2 on mileage

**Toms04compg** · 03-21-2012

.160k no mods at all. It sounds good but ill go check with my hand. Does it have to be warm or no diff

**MoarkatsINmuhtrailer** · 03-21-2012

usually the cat acts up when at operating temp. you could drive around for about ten to fifteen and check it

**MoarkatsINmuhtrailer** · 03-21-2012

id bet on plugs though

**OH4CompG** · 03-21-2012

This is gonna sound silly, but did you check under the hood to see if your supercharger belt is still there? I'm not sure what this noise you were describing is but I know the 04+ gp's show reduced power if you take the supercharger belt is off. Also it will foul the plugs if you put your foot in it with no boost so that would be your misfire code.

**MoarkatsINmuhtrailer** · 03-21-2012

loose tensioner?

**Toms04compg** · 03-21-2012

When i hit it my boost stays up and steady with a nasty hesitation around 3k and up. Wierd thing is in park i dont get the stumble when reving or taking rpm up steady

**Toms04compg** · 03-21-2012

I hear things about this metal ring on plug wires. Is it the ring that goes into where wire meets plug? Could that do this?

**Toms04compg** · 03-21-2012

So it seems like i got steady flow thru the pipes. The sound was like a clack clack clack clack at idle because i stopped as soon as it happened then i turned off car and started it and that noise and sensor was fine it did happen around a curvy road and then i hit a bump and it went off. The belt is there

**blueguy** · 03-21-2012

If there isn't a metal clip inside the wire to connect to the plug, then LOL, yes...that could do it.

**Toms04compg** · 03-21-2012

I was talking about the cylinder metal that the plug wire end goes into

**MoarkatsINmuhtrailer** · 03-21-2012

Are there metal sleeves that the wire plug goes into? If so take them off.

Why take them off? I heard of one case where they might of caused a problem but not sure what happened. I am just asking, maybe I should take mine off too?

**SlowNA06** · 03-21-2012

160k on factory original plugs and wires? Uhhhh

**Toms04compg** · 03-21-2012

Yeah its possible those where not changed ill dig into it after work. I will take the sleeves off. It was kind of that clacking sound on lunch. Now its warm around here first day driving when hot hope its no motor knock. Clogged cat i hope due to im gonna get headers anyway in a couple weeks
