I have got a really annoying problem with my car. Its been there sinse i got it but it now bugs me. When i change gear,bring the clutch up and give it some gas it hesitates(kinda jumps about like someone is pushing the gas pedal then releasing it the doin the same thing again).It also does it when im just coasting and then accelerate. Changed the spark plugs,had the ecu updated,been plugged into a tester,Cleaned the EGR valve as much as i could and i have run some engine cleaner through it but the hesitation is still there.
Anybody know what it could be or exsperienced it before?.
