I was driving my car and I noticed it stutter when I step on the gas, like its choking, what it could be, I checked my oil, and its fine, fuel there is plenty of it, it was doing it from first through fifth gear. What could it be?

 

maybe a little too rich? could be

 

Coudl be detonation. Watch out, what is your setup?

well its a lsvtec turbo with the following:
B18b block sleeved golden eagle
Je pistons 9:1 compression
Eagle rods
JDM Type r head
Port and polish stage 3
Titanium reatainers
Stainless steel valves
Civic type r exhaust cam
Integra type r intake cam
Vortech fuel rail
Spoon fuel regulator
Jdm Dsm 450cc injectors
JG Eldebrock Intake manifold
BBK 70mm throttle body
T3/T4OE Neutec Hybrid turbonetics turbo
3 inch down pipe
3 inch exhaust
External wastegate with dump pipe
15 core front mount intercooler
Pulleys
Cam gears
Type s bov or ssq if desired
Chrome piping
JDM Type r valve cover
10.5 mm spark plug wires
New radiator
New igniter
New coil
Vortech fmu
Jdm p28 ecu chipped with lsvtec program
Jdm type r tranny
Exeddy stage 4 clutch with heavy duty pressure palte
Assco aluminum flywheel 8lbs
JDM type r shift linkage

could it be fault spark plugs?

 

What is your ratio on the fmu?

 

the FMU may be broken, thats my guess. try taking it out and driving out of boost

 

Thats what I was getting at. Sometimes the plates in a fmu will form a small pin hole.

 

how can you fix the problem with the fmu.yes i was running the car without getting in on boost and was still doing it.my fmu is is 12:1

 

Which plugs are you running again? Did the motor all of a sudden start running like this?

My question is with all this money in the engine how come you dont have some good fuel management?? At least do the hack over the FMU. That would probably make your car run alot better. Check your ignotion components as well.

 

well i looked and i have some bosh platinum spark plugs, i know they are not the best but i think that should be the problem too. what do you guys think?
