guys im new here

sorry i try search for 240sx starting problem and found nothing

i have a 1990 240sx se auto

new plugs, wire, cap rotor, and alternator

BATTERY OK

CRANK OVER OK

crank over but no starting sometime, especially when the engine is hot

car idles ok,

problem: under 2000 RPM and when the gas is to the floor , car sputter, RPM drops almost want to stall,

then if i back off the gas it will run ok

no power whats so ever

im thinking throttle position sensor or is there a cam position sensor or crank shaft sensor ?????????? i heard is a common problem

any help would be greatly appreciated

thanx guys

i'm guessing u checked the electrical connections & made sure those new parts are in working order...

mebbe fuel filter time?

did u pull trouble codes to see if it is any of those sensors/circuit wires are bad?

http://www.240sx.org in the FAQs section should give u some instructions/codes if u dunno how to do it.

GL!

time to test starter/wires to it? heat goes up= increased resistance... just a possibility...

no power problem <shrugs> any trouble codes stored in the ecu?
