420A Misfire/Stalling

[Chadmwolf]

The other day I was driving my car and it was just fine. My car has been overheating for a while now but it hasn't been effecting anything besides a little burning oil (I think because I dont see an oil leak/spot anywhere). So I know my head gasket is going. But then a few hours after I had last drove it, I had started it and it was sounding weird(Misfiring I believe) and almost stalling. I have so far replaced my spark plugs the spark plug wires. Could it be the coil pack? or IAC?

Here are two videos of what it sounds like...

Any Help would do. If you guys want me to make more videos I will. I just need it fixed so I can make it to work.

I don't know much about 420a but I have a coil pack that you can buy. It's obx. Pm me if interested.

Before i buy anything else I want some people's opinions. To make sure I know what I need to try to replace.

when you drive it does it backfire at a certain rpm? Almost as if the entire car is stuttering and bouncing. Or do your rpms bounce at a set number, almost like a launch control.

Is the check engine light on? Have you pulled any codes? Sounds like a vacuum leak. Start there before you start throwing money at it. Save your money and diagnosis the problem first.

its really only a problem when i am idling or when I put the car into neutral. My rpms bounce between 200 and 1200. The check engine light is not on.
I have not pulled any codes because I do not have the tools to do it.

What do your old spark plugs look like?

My old spark plugs looked terrible, I would send a picture but I am at work. but they appeared to be burnt at the bottom of the base.
like in this picture...

Anytime I am idling or below 2000RPM, it feels as if I am bouncing kind of. And it sounds louder than it use to be when it is sucking in air, like it is making a higher/louder sucking noise.

I bet your getting coolant in the combustion chamber mine got that bad, the sooner you get that headgasket replaced the better.

How hard is it to replace the head gasket? are there any tutorials for the 420A engine?

Ok so I just went and bought a head gasket set. also bought new head bolts. Hopefully this will solve my problem.

well before you go through that process, do a compression test. To me it sounds like something electrical, like the MAF, or possibly a bad O2. maybe even a vacuum leak, since it goes away when you give it throttle

Take your car to O' Reilly's or Advance and have pull the codes for you....plus it's free.
