sputtering after shutting off and turning back on.

[richard479]

It seems i can never get a break from this car.... After fixing and issue from last week i have a new one. Whe the car is cold it starts just fine and idles fine. But once it warms up if I shut it off and turn it back on it sputters like crazy and bogs for about 5 minutes and then goes back to normal. I've searched but can't seem to find anyone having the same problem. Any help would be appreciated guys. Thanks.

It only does it when hot? My car does the exact same thing. If I drive to the mall and park it and go in, come back out awhile later. Sometimes it starts up and sounds like it's got a set of 280 cams in it. If I give it some gas it runs just fine and I can drive it.
I honestly think it's a CAS, the ignition ignitor, or coil packs being weird. I haven't figured out the cause either sadly. :\

Faulty ISC motor could do this too.

Mine acts like this since pins 4-6 took a crap.

Yup, only once its hot.... did this when i was with a couple of buddies and they where like "woahh that thing sounds so mean" and i just laugh and said its sputtering. i do have HKS 272s but even when driving if there is no load on the motor it sputters. its rather annoying.

Check your spark plugs and coils first. Pull out the multi meter!

i did have a high idle at about 2000rpms, but since i put the cams in its been idleing constantly at 1000.

Make sure BISS is 2 turns out if your ISC is plugged in and working correctly.


Boost leak test?

Boost leak has been done and I'm on SD idk if that matters.my Biss seems to be stuck....it won'tturn anyway.... could this be the problem?

Stripped out or bottomed out?

Maybe invest into a new throttle body?

Vapor lock. Next time the issue happens remove the vac line source from the fuel pressure regulator before you try to start the car to see if it solves the problem. Do not drive the car with the vac line disconnected just let it idle to see if it solves the problem. reconnect the line before you drive it. Do a search on vapor lock its a common problem.

Are you untuned?
Just read your on speed density, If nothing suggested works maybe post a log.(assuming you have link)
