i really dont know whats goin on wit it.. it turns on cool but its jus when i start driving it begins to stutter once it gets around 3 gran and it wont let me go past it.. its like this in every gear.. i think its sumthin to do wit the air flow cuz when i step on the gas it kinda sounds like its gasping for air.. then turns off .. at first i thought it could be the ecu so i bought a new one and that wasnt the problem.. if anybody has any ideas ill be glad to hear them.. thanks..

 

Maybe starving for fuel? Maybe you fuel filter is clogged or you fuel pump is on its way out.

 

i dont think so.. cuz i replaced all that like 3 months ago..

 

maybe the in-tank fuel filter is clogged? This happened to an old Rx7 of mine. Or it could be the onset of a clogged catalytic converter. check to see if your header is getting really hot or red.

 

sounds like its gasping for air??? maybe you have a vacuum leak, check all the hoses for cracks and leaks..
maybe also a throttle position sensor with a dead spot...just a guess on that one

 

thanks ill check that out.. i appreciate u guys..
