HT Leads, Plug Extenders and Dodgy Garage
Discussion
Hi,
Have a little problem with my 5.0 Chimaera. It all started when I stopped for fuel on the way to an MOT. Got 10 yds down the road and it was missing very badly (down to around 10mph until I could pull in).
Through a friend of a friend who had an MOT place down the road they agreed to keep it over night and take a look at it in the morning. I favoured this to waiting around for an hour for the AA.
In the morning I went back to the garage by which time they had *diagnosed* the fault as old plug extenders and leads and ordered new leads. While I am not surprised they needed replacing (on my to do list) I told them there was no way that this was the fault as it was too sudden and on all pots. I suggested they replaced the coil and check 100 Amp fuse.
Got the car back with them saying it needed a new temp sender for emissions.
So I now have the main fault fixed (I suspect it was the coil since it failed after/on a hot start). I have a new gauge temp sender (not the ECU one!!!!)
New plugs and leads directly fitted to the plugs (no extenders). Not sure what make just 'Silicon Power Leads'.
The car ran really rough at low revs and was slow on starting it was also pinking under hard accelaration. A quick investigation showed that a number of the plug leads had not been pushed onto the plugs properly.
This has fixed the slow starting and improved matters, however, it is rough at idle and misses at low revs. Apart from this the car is driveable but still pinks under heavy accelaration.
So....
DO I NEED extenders for the car to run right? I suspect not although I plan to get some anyway (too close/hot) to the exhaust.
I believe the leads and extenders should be non restrictive. Is this correct and would the wrong leads (restrictive??) give these results? Is there any simple way to check this?
I do suspect that the fault is related to whatever the garage did to my car as even after the break down it ran OK once it had cooled off. Other things on the list include:
Stepper Motor
Coil (I do have a new one fitted but not sure what make)
ECU Temp sender (have this is my garage anyway)!!
Fuel filter (They drained the fuel and said it was not in the best state. The car had been left for 4 months so no great surprise.
I'd welcome any comments before I expand the search. Plenty of suggestions for this type of fault from search facility.
Cheers,
Matt
