ok heres the deal. first of all i've searched. but heres the deal i was driving my car today and all of a sudden it died on me. now it will idle good, but as soons i give it a little bit of gas; and let off it will die on me. i don't know what could be wrong. anyone please help! thanks in advance

IAC?

not the iac

Is your car an automatic? When u let off the gas, then the tack goes all the way down to zero and kills the engine?

Describe your problem more. when you give it gas does everything feel normal until you let off? when you let off the gas does it immediately drop to 0 and die or do the rpms bobble then die? give us a little more info.

sorry guys i've been at work so i just got to this. ok my car is standered. and everything feels fine while dirving and then when i let go off the gas it goes down and then about 800-900 rpms it strts to bubble then die. as if it wants to stay on but doesn't. fuel pressure is at 20psi at idle on 440's. the rpms will be at zero and sometimes the speedomter will be at like 10mph or so but that's not ll the time. thanks again

anything, anybody? also i want to know are the sensors the same for the avenger from 96-97 the same as the eclipse. thanks

sounds like you got a vacume issue check all your hoses behind the intake mani, and check your egr hoses, also if you have a leak you should hear an abudance of air like a bad hissssss. what have you done in the last fe3w days to your car??? engine wise, sometimes its the answer to your problems

just an FYI, turn your FP down to like 15psi static. i did today and i dont run as rich now and my gas mileage is good.

check your cam sensor too for your stalling probs. my car wuold idle good then die anytime i would drive it last year from my cam sensor.

ok ihave done nothing tothe car in the past couple of days. and it does not sound like ihave a vacum leak anywhere. well yesterday i strted looking for the problem again and the car won't die at idle anymore, but it won't hold a steady idle when giving it a little bit of gas at idle. this all happened while the car is parked. the cr kind sounds like it has a lope toit from some cams but i have stock cams. thanks

ok guy i really need some help on this it's still causeing the same problems is there any way to check to see if the sensors are good.

ok so heres the deal i've replaced the iac, and no luck car was still being stupid. replaced tps sensor and nothing. replaced the bottom coolent temp sensor and nothing. replaced map sensor and nothing. but heres the weird thing with the map sensor; with the car on i unpluged the sensor to the map sensor. and it will like want to turn off and then it will catch itself and idle good and everything problem still there. but i thought that it will turn off if the map sensor is unpluged? so anybody have any ideas it only happens when i come to a stop. could it be my msd box or anything ignition related. i relly need my car and im getting relly tired with this problem. sorry for the long post. thanks in advance

Maybe you should list all of your mods because you keep springing variables on us. At first post you sound like you have a normal car. Then you bring up having 440's (wich I hope to GOD you have turbo to justify those monsters) and now you bring up an MSD box. Please enlighten us to ALL your mods for a better grip on what it may or may not be.


And just so you know there have been a lot of people on here with MSD issues, you might wanna bypass that whole shitbox and run your car around for awhile and see if that is the problem.

ok mods are howell bottom end kit. je's,eagle rods, total seals, precision sc4431 turbo, tial wastegate, hks, sfmu for 440's, walbro fuel pump, crower valve springs with retainers,greddy evo exaust and that about covers it. my msd box is throwing any codes or anything like that. thanks for the help.

no safc to lean out the injectors? you are probably frying O2 sensors like crazy, might need to get one of them. Any CEL's being thrown?

no safc and no codes. i don't know what could be wrong would the o2 sensors cause the car to do this? it drives fine while driving no hesitation nothing just when coming to a stop. and i don't think it's the msd because i bypassed it and it was still doing it. thanks for the help.
