Hi, Hope you can help with the following issue,

From initial start for cold [but not all the time] there is very erratic throttle response, drives slowly, then quicker by jerking forward feels as though it is misfiring [but the rev counter remains steady!] then after say about ¼ mile or so it'll suddenly drive normally, no further issues, until, i start it again from cold, although during normal driving it will occasionally start to slow with little throttle response, have to stop switch off & restart and that usually
clears it, no warning lights or any messages are displayed, except very occasionally "TRANS.FAIL-SAFE PROG".

Have taken it to the independent garage who services the car, checked diagnostics, it came up with Pensil coil issue which was changed, he cleared all the fault codes, changed plugs air filter etc., but the fault has returned

Any feedback would be appreciated..............Regards Ian
