On the way back from work today, i came to stop at an intersection and noticed that the RPM was dropping and the zed was trying to stall. Kept my foot on the throttle slightly to stop it from stalling, and dove the rest of the way home (was only 500 meters away from my house when it started). Made sure i didn't come to a complete stop cos i knew it would die. Got to my driveway and it stalled a split second before i came to a complete stop. Tried to re-start the car but wouldn't start unless i gave it some gas and even then it was stuttering. Stalled again the moment i took my foot off. Popped the hood and nothing seemed out of place. I had just replaced intake pipes before i left for work, but they were still on fine. It may also be worth mentioning that i also removed my BOV's at the same time and stuck a screw in the vacuum lines to block them, but it seemed to drive fine until that last 500m. Any ideas? What should i be checking in the morning when it cools down? //Edit: It's an Auto TT btw, and it does start if i try the ignition, it will just bounce the revs one or twice and then cut out again.
Had similar symptoms when my coolant temperature sensor sensor was going out... sent a wrong temperature reading to the ECU, resulting in flooding upon start and running rich or lean once it had. Pull that out and check for corrosion. Give it a clean and lube and try starting up again.
You mean unscrew it and pull it out yea, not just the plug? Will do that first thing in the morning. Can it just happen halfway through driving though? I had the stereo on so i wouldn't have been able to hear any hissing or popping noise or whatever, but once i realized i turned it off and i couldn't hear the auxiliary fan running. If it was temperature related, surely the fan would have turned on? The temp gauge didn't move either. Also running rich/lean i can understand, but this can't be considered "running" at all, it barely starts and then it dies, and even if you keep your foot on the gas it stays on but the RPM is dancing up and down. It always starts first time so it's not an issue with the starter motor or anything either.
I just meant unplugging it and looking for corrosion there, that's all mine needed. When it happened to mine, it was after a friend of mine used (and gunned) my car. When I started it up not long after he got back, it was there immediately. For me, when driving the RPMs would bounce anywhere between 1 and 3k, then past that it would run "smooth" in terms of power delivery.
Oh, well i did that already, and there was no corrosion. Gave it a wipe down anyway to remove dust/dirt/whatever and no difference. You sure are trusting, i don't let anyone drive my Zed without me in it lol.
Look for dislodged vacuum hoses just underneath where the intake pipes clamp onto the plenum throttle bodies. One on either side. Trace the one on drivers side back to the accordian-style large turbo inlet pipe. About 6-8 inches long.
Zed4Life: The vacuum hose from the "accondian-style" intake pipe on the drivers side has been blocked. unv300zx: removed my AFM, checked that + my pod and both looked fine. Gave em a clean anyway, and no difference. whopper: That was the first thing i checked, yes they are still in. Gonna remove the intake pipes i replaced yesterday and have a look, but AFAIK all of the vacuum lines that i reembers seeing are weither blocked or still attached. It can't be related to me removing the BOV's, can it? It's an auto so they don't do much anyway, and i made sure i didn't suddenly close the throttle while boosting.
Yea otta replace my PTU sometime lol. Found the problem, one of the PVC hoses at the top of the plenum had poppped off, strange that they have no clamps on them, but oh well
Didn't want to make a new thread so figgured i may aswell post it here: For a few months now, i've had a little stutter when i start moving from a complete stop. Example: I'm at the lights and they turn green, if i open throttle too fast, my RPM will actually drop first before it starts climbing. The faster i open throttle, the faster it drops, i haven't tried it but i'm assuming that if i try to floor it, it will probably stall. I've just adapted my driving to it and now make sure i start accelerating at a sensible rate, but i'm just wondering what it could be. Other than that though, it doesn't affect the way the car drives or anything as far as i can tell. It may also be worth noting that while the car is still cold, if i step on the throttle just slightly while it's in Park, the RPM will again drop before it goes up. This goes away once it has warmed up though. Any ideas?
