when accelerating car sometimes start to sputter at 2500. dont think its the maf because y would sputter all the time if i was but its only when accelerating in first. most times its normal. tonight i think it went into 4th and did it. not sure because i could not hear the noise and it picked up well. any sugg

 

i also have a bad battery but high current alt. think the battery could do it?

 

I too have the same problem... not everyday but when Im not thinking about it at all... it will do it to me. Scared the **** outta me the first time it did it.

Could be cracked coils?
Vacuum
Clutch slipping?

 

i would think clutch. i just replaced coils and vacuums are str8

 

"Sputtering" (short periods of seemingly misfiring?) due to clutch? - definitely not.Battery serves no purpose on the car if the alt is working as it should once the engine has been started. Is your alt running on a constant output voltage of 13.6V or above irrespective of the motor speed and vehicle electrical load?

Thinking MAF, coils (even if they were just replaced), quality of earth connections in particular but others in general, TPS, FPR (low fuel pressure > lean mixture requiring more HT to ignite)

 

yeah. i think i see the problem. will be fixed in a couple of hours

 

think it tps. runs fine with the tps unplugged but its idle is high. just replace 2morrow

 

still here. now takes like 3 cranks b-4 it starts. what could the fpr cause?

 

if it starts i have to give it gas and slowly let it drop to idle speed

 

A bad spark plug would do it.
Or bad gas.

 

im using 6 bosch platinums. which i heard are not good wit our engine

 

Confused................

What have you done exactly as the problem description seems to have changed

Bosch plugs have been moaned about a lot here - the moaners say their problems disappeared with NGKs

 

nothing i didnt even change the sensor. it just doesnt want to start. have the ngks and are going to install now.
