hey guys lately my car has been cutting out on me )like that feeling when your running out of gas) and my car has 450cc injectors with the stock fuel pump,so i was pretty sure thats why it was doing what it was doing so i put in a walbro 255lph pump and still the same thing.the car has brand new cap,wires,rotor,fuel filter,fuel pump,spark plugs so im not really sure what it could be.sometimes ill drive and it will run great but then sometimes it will be so bad it will keep on shutting off on me...anybody have a shot in the dark as to what the **** is going on with my car lol.

Did you install 450cc injectors on your stock engine with your stock ecu?

no his boosted d16z6 has a custom tuned ecu and DSM 450s.

I've seen DSM 450s act all ghey a few times on a few different cars (thats why they aren't my first choice of injectors and why i don't recommend people to use them), and its possible that could be you're problem. But instead of just replacing parts (a fuel pump was a MUST on a boosted setup, so that wasn't a waste), i would suggest just taking it to a shop and having someone look at it.

Did you install you're catch can yet?

That's cool a turbo engine I didn't know.

imported_italstallion

yeah it could possibly the injectors maybe i should swap them out and try it with someone elses injectors and see if that works???

i would also try swapping out the dizzy, if you have a friend with a d16z6, try his.

yeah but i was thinking it feels fuel related for sure.if i were to get rc 440's would i need u to retune it?

just make sure to get low impedance (peak and hold) b/c if you get high impedance (saturated) you will have to remove the resistor box.

I would say that you could prolly get away without a retune (although its a good idea to retune really if you change anything about the setup), since you were using 450s and would then be using 440s....not too much of a difference IMO.

imported_italstallion

ok well first im going to try an injector cleaner and see how that works.

imported_kungfugrip

my car was doin that as well due to a clogged cat.. yesterday the car wouldnt even start.. replaced the cat and it was fixed

chris_si98

injector cleaner isn't magic pixie dust. It's not going to make your car not bog lol

imported_italstallion

im not sure if its the cat because its brand new like 2 months old its a magnaflow replacement and i am turboed so it could be i guess......... but why would it only do it sometimes?

chris_si98

Man

It's not the cat, lol.

imported_italstallion

lmao ive narrowed it down to the dizzy or the injectors at least.. lol

chris_si98

do you have a multimeter?

I can teach you how to diagnosis your distribuator. Its not that hard..

imported_italstallion

imported_italstallion

imported_kungfugrip

nevermind.. my car keeps cuttin out again.. and the idle bounces ****in everywhere or gets stuck at 1500
