Hi all, Im hoping someone may have some advice on an intermittent power issue im having. When I accelerate up through the gears I often get power coming through but not smoothly. Then I get up to speed say 70mph in 6th and the power is not coming through at a constant rate - it seems to stutter slightly as if holding back - it can do this on and off over a few seconds and then calm down - I think mainly during the warmup period, first 15 mins of driving.
The car is new to me so still getting used to it. Its on 108k and could do with a cambelt change, its only done about 10k since last one but 4 years old. Its also had a remap before I bought it and has an old K&N cone filter on. Not sure what other engine mods its had. The issue doesnt seem excessive but worrying, no dash lights etc.
I need to get it on a code reader but Im wondering if it sounds like a turbo issue, crank sensor or maybe fuel pump?
Any advice appreciated! Enjoying the car apart from this and lots of small jobs already done...
