I've managed to get a couple of screenshots from the scan software with the engine idling, still trying to work out how to record the data so I can go out for drive with it running.

Annoyingly I couldn't get it to play up when starting, must have known it was being filmed! Did get a recording of the engine at idle and when blipping the throttle, please note this is a petrol (although it sounds like a tractor!):

Thanks for the replies.

 

 

Hi Oliver,

 

OK, so the car starts 1 in 10 times, and then dies straight away? if thats the case, your missing one of the big three - Spark, Juice or Air, by the sounds of it your getting them all forced on the same path at one point but they lose sync and thats what causes it to blow off.

 

I would suggest the first thing to do is get a leak off test done, check what levels of fuel you are getting out of the injectors, this will tell you if any are running rich or lean. You might find that you have a fuel delivery issue, either a bad filter, or perhaps even a bad pump, so check these two for leaks/

 

Secondly I would suggest you check the air filter, make sure its not turned to stone with all the crud its collected as this would stop the car breathing, removing the air.

 

Sounds like you have resolved the spark anyway, leads coils and plugs is definately the right way to go, but I would suggest you check that they are gapped correctly (I believe the book says 1.3 but they should be 1.0mm) if they are gapped differently try one of those two values until you find it improves.

 

You might have a sensor fault, it could be the crankshaft sensor throwing it to pot. If you have just a bluetooth OBD, its not guaranteed to pull the results as it doesnt pool codes from all modules. If you have the trip computer, you can check for error codes on the instrument cluster. If you need further code reading, you would need to get a different bit of kit, I suggest a modified ELM cable and FORSCAN software. This will query all modules and will allow you to get a better picture of what is happening on your car.

 

Hope this helps!

 

It actually dies 9 out of 10 times. The revs go up just over the 1k mark and then drop, my crude solution at the moment is a boot full of throttle when starting the car. I have, however, noticed a bit of a gasping air noise when blipping the throttle so will make sure there are no leaks between air box and throttle body (the filter has already been replaced). The fuel filter hasn't been replaced, are these still under the car near the tank (replaced one before on a friends mk1 focus, was a PITA).

 

I'm using an ELM cable and PCM Scan software to look at engine codes. It does give live reading of quite a few parameters, would a screen grab help?

 

 

Do you have access to a compression tester?

 

I don't, no. Have looked at getting one before but were told the cheapo ones are next to no use. Would it be worth getting this done at a local garage?

Is the battery getting/holding charge?

 

I had something very similar on my previous car (MG) and the alternator was giving up the ghost and not fully charging the battery.

Is the vibration through the steering wheel or can you feel it through the seat?

 

When you had the front wheels done did you get the rears checked for alignment/balance?
