so today i decided i would put some injector cleaner in my winter car (02 nissan sentra) to make it run better , cleaner etc… well i bought lucas upper cylinder lubricant from Canadian tire,so i filled up my tank and put some in, on my way home from kitchener when i got off the highway i geared down and the car started to sputter, so i turned down the tunes to listen , everytime i bring the car up to 3500 rpms the car starts to sputter and will barely accelerate until i switch to the next gear, but once i hit 3500 rpms again the car starts to sputter and wont accelerate any more(this happens in every gear) , never did this before only started once i put the injector cleaner in …? anybody have any thoughts on this? anything i can or should tdo to fix this? thanks

then that changes things. pull out ur spark plugs see if there f’d up blown or anything. also make sure ur intake is not kinda off a little maybe it was loose and got blow off a little by pressure. check vacuum. first start off by pulling ur plugs. and check to see if u got spark in all cylinders aswell.

check for cracks on the ceramic white side of the plugs as well, happened to me i didnt notice when i first pulled the plugs out they seemed fine but the ceramic parts where cracked. if that is all well test ur injectors.

ok ill do that but, the car runs perfect at idle and when driving casually like if i shift before 3500 the car runs how it always has and should, its not often i bring it up that high before shifting usually 3000rpm tops before shifting, so wouldent that mean that the car has spark in all cylinders?..

yeah im sure it has spark in all cylinders but since ur ognna pull out the plugs n check them u mite aswell check to see wont hurt . but yeah i had blown plugs before and the car drives perfect until u hit the gas and drive a little faster.

make sure the maf plug is in properly. could jsut be a loose plug.
