Chrysler 2.4 #4 cylinder misfire

[Poopshinanigans]

Car was running perfect yesterday (sunday) but today i start up the PT (2001 with almost 91K miles) to go to work and the motor is running super rough. It was similar to when my cam shaft sensor was going, but it wasn't throwing a code. It stopped being a dick when it got warmed up, but it was doing the same thing when i was driving home. It finally threw a code when i was driving home, P0304. This code means that it's detecting a misfire in the #4 cylinder.

Anyone with the Chrysler 2.4 (turbo or non) have any problems like this arise? Could it be that i need too replace my timing belt soon (per owners manual)? I'm going to see how she runs tomorrow, if this shit still happens i'll take it into the shop on my next day off. But if anyone has some insight, please share it.

Thanks guys,

Poops

Could just be a bad spark plug or wire. I'd just change that first.

I think doing that will be pretty easy, the number 4 can be changed without taking the intake manifold off. I'll give that a try and see if the plug is fouled any. This seems weird because i drove to chicago yesterday and the thing was running like usual ( which for a PT isn't great, but i deal).

It happened to the camaro once. Was driving fine and out of nowhere started hesitating and misfiring like crazy.

Could have melted a wire. You have wires and not coil on plug right? Doesn't take much to damage them. Yank it off and borrow one from another car and see if it goes away.

well primalzer is coming over today, maybe while he's changing his oil i'll do the ol switcheroo.

 

[Bob Kazamakis]

Do it. He won't notice.

Race my bike you pussy!!!

I've had shitty coil packs do that sort of deal.

 

[Poopshinanigans]

This coil and plug wire set have been on for 50K miles, do you guys think its time to change them? I've just recently change the plugs over the summer.

 

[Bob Kazamakis]

I bet plugs are fine. My bet is a wire though it could be a coil. Can they test those at autozone? I'd just switch with primalzer

 

[skeezer]

be a man and pull the wires off the coils and see if you're getting spark

 

[Bob Kazamakis]

Could be a weak coil too.

 

[Poopshinanigans]

well primalzer and i decided to go buy a timing light to see how things are going. There is spark going to that cylinder and the fucking thing is running fine today. just to make sure it wasn't caused by an injector we Seafoamed the fucking thing. We'll see if it has trouble tomorrow.

Idk, for some reason after I went over to this kids house my car was SIGNIFICANTLY slower, got worse gas mileage, turned blue, and became an auto.....did you think he pulled the 'ole switcharoo?...IDK, i did hear the PT's turn colors in the fall...

 

[Poopshinanigans]

the thing is running fine now, no CEL. The seafoam did the trick. Though i was hoping for a drastic increase of performance and gas mileage, oh well.

The car must've been sitting and not getting properly warmed up enough. A bunch of carbon had built up, and it just needed to be cleared out.

I think the bitch be gettin old and parts no worky like they used to.

What ever happened to you getting a new car? What happened with the svo?

 

[Poopshinanigans]

I tried getting the TDi sportwagen a couple months ago. But VW doesn't let you order what you want from the factory, you have to wait till something close to what you want comes into the dock. So i'm waiting for the '10.

SVO is still sitting in the driveway. I've been busy with work and lazy on my days off.

sounds like vw is a piece of shit company

i wouldn't go that far, but yes, they have odd practices.
