righto, i've had this up before but nothing seems to have worked.

 

It started about 50miles after a spin off with no impact damage to anything further forward than the doors(no fuel lines crimped). thought may be completly nonrelated.

 

It just didnt want to accelerate, put-put-putting under power.

took it home and tried it a couple of days later and all seemed well untill after about 50 miles it started to do the same, but not as bad as before, could still accelerate but only gently.

Went out in it a couple of other times and it was on the whole fine (mabe a single misfire once evry now and again)untill...

i was out in it most of the day without many problems and got into town and it would barely manage to pull away from a set of lights or up a hill.

Took it home. Left it to cool (2hours max) and it was fine untill it got hot, now it has started to do it as soon as it is warm.

 

i have changed the oil, all filters (air, oil and fuel), spark plugs, cleaned the temp sensor (little yellow plug at center front) and changed the coil pack plugs as these were brittle and shaking loose. I have also put a new exhaust, cats back, on since if it makes any difference.

 

now it all goes a little over my head with injectors and god knows what else that may be wrong. However as it only seems to happen under full throttle and when warm which would suggest to me some sort of sensory fault. Possibly one of the coil packs is caput, how would i go about checking this and what is the likleyhood?

 

please help as this has me on my knees close to tears:headvswal

 

also if anybody knows a good garage for 300s in edinbugh as the one listed's knoledge of the car was, no offence, thouroughly pants.

 

Cheers, Jamie.

Righto. thought id better round this off incase someone searched this tread.

 

The main problem was that the timing was out by a bit. The CAS plug may not have been in properly and the det sensor is shorting or just plain broke and has now been bypassed with a resistor jammed in the plug.

 

it is now running with full power but can be a tiny bit hesitant or very slightly jerky (sounds like the CAS plug may need a clean or the timing is still a bit out)

 

Huge thanks to BIGSSS for most of a days fettling and switchig parts, Berrica for the timing and datascan which showed the det sensor fault and the chap (whose name i have sadly forgotton [will try to remember to rectify] )at hermiston gait meeting that gave and fitted the resistor.

 

jamie.
