my cars not running, I NEED HELP!

[ta_ma3750]

im having troubles with 240 whenever i start it it dies unless i give iy gas and if i let off the pedal too quickly it dies so i have to ease off the pedal very slowly and if it stays running the idle is real low like 300 rpms and ive checked the ecu self diagnose and it came up with no problems Please Help!

you can adjust the idle on your car with the ecu. it has a dial that can be turned in small increments to boost idle. check your fuel pressure after you make the adjustment. There is a write up in this forum some where search for it before doing this for proper settings your soch should be idleing between 700-900rpm. I had a similar issu and this solved it for me.

well before all this my car was running premium and the problems just came out of nowhere, and my ecu said its running rich

I thought in the first post you pulled no codes? Anywho check your MAF clean it if it's dirty check fo leaky injectors...have you tuned it recently? Could be that you temp sensor is stuck causing it to dump fuel...bunch of things but as far as the idle try the adjustment on the ecu to smooth it out and go from there.

no i just checked the self diagnoses on the ecu and it came up with a 55 which is no problems according to my chilton and my injectors arent leaking but may be fouled due to a dirty *** fuel filter that i switched out and no i havent tuned it but ill clean out the maf and work on the mixture

Yeah I would do a basic tune up plugs wires cap and rotor run some good fuel injector cleaner through it or search for injector cleaning could have some debris in your injector that happened to my wife the other week, so i don't know what brand she used but run some through it once a month...

i recently replaced the plugs and wires and i already run octane booster and fuel system cleaner once a month but ill try replacing the cap and rotor
