sr20 cuttin out at higher rpm's??????????

[arley23]

also check all the spark plugs for maybe a melted tip it happened to me one time

^^ You couldnt have said that in one post, did you really need two?

i ordered the recirculation kit. I haven't had time to check the timing yet. I moved the fpr all the way out til i could hear if flooding in the idle and it still stalled out. Is there a chance it could still be the fpr?

I had the same problem, car would cut out liek a fuel cut around 4000 or so, but at a standstill itll rev without any drama. My problem was with the filter.. or a lack there of (long story). Anyway, check your filter, check your MAFS, if you're running stock boost I doubt that it's the fuel pump (although you should be getting at least a 255 or z32). Anyway, after I sold teh car to a friend of mine, he slapped on the filter i bought for the car and problem solved.

[Vegascorbin]

Are you saying you changed the Air Filter and that solved the problem?

LOL, are you the nico anal police or what?

For your information, there is no such thing as 'failed detonation'. You don't want detonation; it's bad. Failing to detonate (so to speak) is a good thing. You want ignition. To further correct your statement, I think you are referring to: detonation, afterfire and spark blowout.Detonation would not be the case here. Nor would afterfiring as the OP would obviously be freaking out about the sound of it. It is probably spark blowout which can be checked with 20 thou spark gap to ensure it isn't blowout. Alternatively, it could be a bad MAF or poor CAS wiring, etc.

Side note: if you are randomly fooling with things to that level, you probably need to find a local enthusiast or a speed shop to checkit out for you.

He was running all over the forums doing stuff like that, every thread I opened there he was with a couple of useless comments in separate posts, it annoyed the crap out of me, so I said somthing, there is a reason his post count is zero, he was a spammer.

You are correct sir, I did mean failed ignition, when you type that much in one sitting you are bound to make a mistake or two, I'm not a very good typer, and my grammar and spelling suck. I was trying to get the point across as simply as possible, I may have skipped a few minor details in lieu of being easily understood by all.

[Miller White]

It has a walbro 255 and a new hks air filter on it. I've also tryed several mafs. Could the CAS be bad?

pull out ALL 4 spark plugs and check them for cracks, or better yet, just replace them all. I chased this issue about a year and a half ago, ended up being cracked ceramic on the spark plug causing the spark to arc off the head thus making it break up like it had an ENORMOUS misfire

[Miller White]

I just replaced all the plugs and regapped them. They were gapped to .040 so i regapped them to .028. But it didn't make a difference. I'm still waiting on the recirculation piece for my bov tho hopefully thatll fix it. In a couple of weeks im goin to buy a new fuel pressure regulator and an apexi safc to run a z32 maf i got, maybe that'll help. idk

[Miller White]

The last time i drove it i noticed the wastegate vacuum line was off. I put it back on, but it didn't make a difference. Could this possibly have anything to do with it?

[Miller White]

Today i recirculated the bov and put new ground wires on it and still nothing has changed. Im going to clean and oil the wastegate tomorrow because a few people have told me it could possibly be sticking. and i finally bought an electricity tester thing to so im goint to check the throttle position sensor. Oh, and the other day when i first took off and ran through 1st gear it actually ran all the way through to bout 6k when i shifted and when i threw it in second it went back to stalling at around 4k.

[MeanGreenS13]

RE CHECK those plugs... im serious RE CHECK THEM... i had this same problem, recirc and all that never helped... RE CHECK THE PLUGS!

[MeanGreenS13]

oh yeah, and its called a multimeter not a electricity tester thing lmao

[Miller White]

The plugs are good

[mopower13]

I had a '75 280 that did that and it turned out to be the ignition computer I would probably check ther first

[Miller White]

Do you mean the ecu? I had a 78 280z. it took my virginity. lol

[Miller White]

When i took the wastegate off i noticed the exhaust manifold and the downpipe were loose. They were so loose i could see light through them. Could this be why it was stalling?
