:mad: l get a pretty strong stutter when in gear at lights and sometimes as l am driving. Just had engine replaced and engine has around 60 000 kms on it replaces spark plugs and some coil overs filters. Check engine light has not come on, any ideas on this????

fuel filter and or fuel pump maybe.

it did this a little when l first got my car back from the engine R&R but stopped when l ran my gas tank empty and filled it up again, could it have anything to do with a sensor or the EGR valve?

l would like to correct it to surging as a better phrase

there's a lot of things that could be wrong, would check to see if any code are being thrown (even if the check engine light is not on) and go from there. I've seen O2's, IAC, and fouled plugs (from oil dripping down the cylinder) cause the problems. I would personally do a complete tune-up and go from there.

l am positive it just had a complete tune up 3 mos ago when l had the engine replaced :confused: l will say this, it still starts on a dime no problems there and doesn't stall yet just surging, it frustrates me cuz l just put all that money in the R&R lol

go have the codes ran and see what you can find
