PT Cruiser A Classic

Your code is telling you that you have a random misfire on cylinder #1. Before you do anything else check the ignition components on cylinder #1. It's not lying to you

if you need a coil pack tack a picture of the plug and I will check what I have as I have a couple off neons.

Like being in court this answering all these questions, I stated that I started maintaining the car at 80k miles, might have been 60k miles in which case that was when it had new plugs, it has never had a new set of ignition leads. I did have the plugs out back in March because the No 1 spark plug recess was full of engine oil, apparently some one slipped when putting oil in and it wasn't me. I thought that might have cured the misfire back then but didn't, as far as I know apart from plugs a battery and the third lot of front suspension bushes the car is 10years old and as it left the factory..well yes oil and air filters excepted, it also had new anitfreeze a couple of times.

Now i'm up for it this weekend will see some investigation and I will keep the masses posted.

Hey, you asked

If it's a twin cam engine, i bet that the valve cover gasket is failing which is why the plug recess is full of oil. I'm not talking about the gasket that goes across the parameter of the valve cover (or cam cover) but the O ring gaskets that seal around the plug holes.

As far as I know only the SOHC was put into the export models,
and it is a common fault for the O ring gaskets to to go in the
rocker cover on these engines and end up with oil in the plug
tubes.

For those who follow these thread's, today saw the EMU out, and plugs cleaned, top end of the engine stripped so I could get at things and an investment of £3.99 at Maplin for some Spray Electrical Contact Cleaner, got most of the Wiring harness for the engine where I get at it and see what's what, I cleaned all the sensor sockets and sensor plugs some where a bit green and gummy, a new coat of contact grease and re-installed, couple of bits I couldn't do where the knock sensor and the CAT oxygen sensor, wasn't going to lay on the ground as it was wet..

Plugs came out, ingintion pack and leads off and all cleaned and checked, again there was traces of oil in 1 and 4 plug holes so going to keep an eye on that and yes mines a twin cam jobby. Plugs looked ok and leads checked out to the lower end of the resistance range, swapped No1 and 4 plugs and leads so if there is a problem there hoping the miss transfers to No4 cyclinder.

Long story cut short the test drive was awesome, can't remeber the last time It had as much power torque and such a clean pick up, mind you never has been a racer, but what a differnce, came home like a dog with to wotsit's, even the error log was clean.

Should have bit the bullet long time ago rather than putting it off, 4 hours work and bit of cleaner and magic.

Thanks for all those who posted I have taken on board all the advice and now not so frightened of the black art of engine management systems. Thanks again

Sounds like you've had four very productive hours then. Result!

[Maaarrghk]

Glad it's sorted ajmin.

Always worth just checking the simple stuff first, especially on an older motor.

I remember the first time I saw the artwork for the Cruiser, Crossfire and 300 and thinking "Ooo! Didn't Chrysler go bust? Nice motors but probably just artists impressions and they'll never really build 'em".

I was stunned when they did just that, not on just one car, but on all 3! Always loved the PT's "Factory Hot Rod" looks. Didn't they actually offer black 'n' flames as a paint option at one point?
