pureguava 59 Posted August 21, 2020 Report Share Posted August 21, 2020 Hello 2000 V8-GT all seems to be fine down low and no CEL or codes ...... when I really floor it and get above 5000 revs I get what seems to be a miss fire - The engine kinda looses smooth acceleration and a bit of loss of power. It’s only above 5000 rpm I wonder if it’s coil packs / plugs / leads so I will change these....... Any other ideas ? Quote Link to post Share on other sites

andyblackman777 46 Posted August 21, 2020 Report Share Posted August 21, 2020 Spark plugs! Mine was exactly like that and one spark plug had failed! There is a thread about it. The threads authors misfire was a faulty alternator. Quote Link to post Share on other sites

pureguava 59 Posted August 26, 2020 Author Report Share Posted August 26, 2020 Thanks for all suggestions - I have a feeling it’s the plugs / leads / coils .... Will replace Monday and report back Quote Link to post Share on other sites
