Yeah it turns out I had a similar problem, the boots on my coil pack were completely worn and the plastic had started to crack and expose the metal so I've put in a new coil pack and all is grand! Thanks for all the help

Right changed the plugs! But while I was changing them I noticed that one of my rubber boots for the coil pack had split and was revealing the spring... Could this be causing an infrequent miss fire? Would it be worth changing the entire coil pack or just the rubber boots?

Just checked the plug as well and all is good, then is no damage to the plug whatsoever

Just checked the o2 sensors with live diagnostics and they are okay, I'm getting +98% on fuel trim bank 2 though and around -1% on bank 1... That can't be right can it?

So it's now idling fine but as soon as you undergo hard acceleration, she stutters and miss fires. Not enough to throw up a fault though...

I'm going to check later I shall let you know. They were changed only a few weeks ago but I'll still check them the engine was running rich until I changed the MAF, could that have damaged the plugs? And yes I'm just getting the P0303 code.

Ah yes sorry I mean throttle body! I don't know why I keep calling it a carb! I'm talking about the but this sits on top of the air intake with the butterfly valve inside of it. Which yes is the throttle body. We've rectified this problem however, this was being caused by the fault MAF, it's just the miss fire to solve now

No other codes just the P0303

I haven't had it in a while though but the engine is still miss firing, not as frequent as before but it's still there.

Hmm, I really wouldn't have thought it would have been the spark plugs though, recently had new ones put in but I'll check them. The engine was running rich until I changed the MAF. Could that have damaged the plugs? How would I go about accessing the leads? Does the coil pack just pop open?

Ah yes throttle body! Don't know why I kept calling it a carburettor! I've just drove her this morning and it's occurring far less than it was yesterday, it's still inconsistent though. I'm going to check the spark plugs later. Will keep you posted

I followed the guide to cleaning the breather system on this site and it explained cleaning and checking the carburettor. Didn't think it could hurt, could it?

Yeah that was my worry, is there anyway I can prove for definite that it is the coil pack and not an injector/fuel problem?

Oh I should also mention that when we were fitting the carburettor back in, the fuel line wasn't fitting snugly onto the carb. It was throwing up the fault code P0170 which ended up being the fuel trim and seen as that was the only part of the fuel system we touched we assumed it was that. I tightened the pipe with a jubilee clip and the fault code went away but the pipe itself is slightly worn... Don't know if that would contribute to the miss fire?

So changed the MAF sensor today as I was not getting any info on the live diagnostics. Recently serviced the car and cleaned the breather system with carb cleaner (including the carb itself). I now have the problem of the car miss firing in cylinder 3... Some of the coil pack boots are worn and number 3 was significantly worn but I swapped the boots around and it's still number 3 miss firing. I haven't checked the plugs but they were changed a matter of 3 weeks ago, I have also thrown some injector cleaner down its neck a few weeks back. The fault codes have been frequent but only once did I get a fault code about the coil pack. This was before I changed the boots around, yet cylinder 3 is still miss firing. The miss fire is infrequent. Could it be the coil pack? Or would that provide a consistent misfire?

We can now smell fuel after she's been running for a while... The bottom pipe closet the the front of the car on the carb is slightly loose... That's nothing to do with fuel is it?

It's also worth noting the cat is getting really hot! Just done a drive test and it still drives like it should though, just the idling issue
