car starts then dies

i have searched the internet forever and have not seemed to see the same exact problem.

ok my car starts fine when its cold but when im driving it studders just a little but not that bad all the time, but after driving for short distances like 10 miles and stopping the car like at the mall, when i come back out and try to start the car it will start fine, but then the rpms drop and it dies unless i hold the gas just a little to keep the rpms steady for a little bit then it runs fine untill i park it again i get the same thing. but after the car cools again it starts fine.

ive replaced the coil and igniter (is anything else in a dizzy able to go bad?) ive done a full tune up. i dunno, its kicking my ass though.

Had something similar with a bad headgasket... could be a lot of things though, and a compression test would be a good starting place.

before i did mpfi about 2 months ago the car ran fine, ive checked and rechecked my wiring, only thing i can think of is the dizzy looked a little rough that i used. is there anything in the dizzy that could go bad besides the coil or igniter? maybe my head gasket could have went. i just hope after i swap my b16 this problem isnt still there. could it be an alternator?

could be the dizzy...there are sensors in there. I would rule out the alternator. Do you have any check engine lights at all?

nope none at all

nope none at all

I would assume it's something fuel related, or a faulty distributor then...but i'm leaning towards the distributor. Find a friend's distributor and swap it to see if it affects your car for the good. Or, you could always buy a new one from autoblown and then if it doesn't fix your car, just return it.

If it's not the distributor, then try new wires and properly gapped plugs.

ive recently got new plugs and wires, so ima go with the dizzy

generally you should first diagonis if it's an air, fuel, or spark problem.

I don't think it's a head gasket as you said this started after MPFI swap. you can check your coolant and see if it looks cloudy like chocolate milk...that would be a bad gasket. and you would be over-heating

try another dizzy and if it doesn't get better you know it wiring. the only things to go wrong inside the dizzy (excluding coil/ignitor) are the cam sensor & crank (#1 cylinder position) sensor....we've seen the one come loose often.

silly question....but you are using a Si dizzy, right?

yeah its an si distributor lol thanks for stating the obvious though never know.

but yeah when i first got the dizzy from the guy, i took the cap off of it and it looked really bad on the inside, carbon shit all over it and the connectors dont fit tight, and also when i first tried to start the car after i finished the mpfi swap it didnt start untill i took the dizzy off and put it back on, so im guessing that may in fact be it, im going to buy another one as soon as i can.

p.s. also after i finished mpfi my car whistles loud as hell when i accelerate and i dont think its vaccuum the lines.

after a mpfi swap huh....................well..................my conclusion is:

1) short in the wiring (can be checked with a multimeter)

or

2) ecu

or

3) dizzy is crapping out.

keep a multimeter in the car. next time it craps on you, take the multimeter out and see if your recieving ign1 and ign2. a helms diagram would be useful for this ;)

i always have one in my car, but whats ign 1 and ign 2?

ignition 1 and ignition 2. helms should degsinate it as ig1 ig2 or ign1 ign2.
