Hi guys and girls,
We've just bought a 2006 2.0 sport. She's running rough, generic code reader came up with p0301 misfire on cylinder one. I have changed the plugs, fitted a new coil pack and checked as much wiring as I can but it's still there. There doesn't seem to be a spark as everytime I take the plug out after running it's wet with fuel, anyone have any other ideas? Can't get it plugged in to a proper diagnostics machine for a few days so I thought I would ask on here!
Thanks!
Dave

 

For all reading this.... if you own and intend to DIY work on any vehicle manufactured from 1995 and newer make an investment on a good quality Diagnostic Tool that you can PLUG into the DIAGNOSTIC CONNECTOR of your car!!!!!!!!!!!!!!!

DIY will often start replacing parts associated with a engine code. This is not and never the best thing to do because unfortunate as in your case you did not solve the problem. A DTC is simply the first step to a processes in determining the trouble and not always a single part. My suggestion is to first reinstall your old parts , clear and re-set both the ECU for codes and the monitors and drive the car at least through 3 or more complete drive cycles. If you get a DTC log it clear it and continue to drive to complete the drive cycles.
Other wise look for a Technician Problem solving chart in a Factory service Guide on the proper steps to resolve your problem. I think you will find that is is check each part before simply replacing random parts.

Here is the thing, should you give up and take it to a shop make sure you tell them everything you did including any parts you changed. There is nothing worse when a customer brings me their car to fix and neglects to tell me what they tried first and I always find out what they did when I am service their problems anyway ... if they had told me upfront it might have saved them a few bucks on some basic diagnostic charges... LOL

 

Well..... Thanks, unfortunately some of us don't have the option due to work commitments and childcare to be able to drive a car 20+ miles (on 3 cylinders) to a garage to get checked over.

I'll ask my dad for advice next time I want a lecture

 

Ok well you thought it was a lecture and read what you wanted into my response missing the points....
Buy a Code reader
Don't randomly start changing parts!

I could have given you other things to check like doing a compression possibly followed up by a leak down test, Checking the ohms of the fuel injector but given you were already on a parts changing/solving path I concluded you most likely didn't have these essential other tools or equipment to use to check things ?

Good Luck with resolving your problem with your busy schedule.

 

I have a code reader. Came up with code p0301 muss fire cylinder one, so checked and the plug was wet so obviously no spark, so the instant thought is plug-coil-wire..... I'm not randomly changing parts I was working the process in the most sensible way I could given the circumstance. I came on here hoping to have some knowledgeable people offer me some advice, I'd have taken the car to a garage straight away if I could, not ask on an Internet forum, but again working with what I have given the circumstances

I have managed to get a mobile mechanic to come round and scan the codes so I now have more of an idea what's going on.

 

Dude, you come hear and asked for help... this is what I gave you by your own words " knowledgeable people offer me some advice"!

You simply getting a "SINGLE" DTC and a wet spark plug is not CONCLUSIVE to start replacing any parts. When you do this way of problem solving many you may inadvertently create other problems that will add to the original issue.

Hopefully you got a Mobil *Automotive Technician trained to diagnose and know how to diagnose a DTC(s) properly and not just a "mechanic"? There is a BIG difference between the two regarding training and certification levels and not just simply knowing how to R&R parts!

I suggest you take a breath get off your defensive posture about my responses and go re-read my suggestions. ; )

BTW key in on *my mentioning customers....
