Left my Z the other side of town as it just cut out on me and failed to restart.

 

Initially for the past few months, occasionally on warm start up, it'll missfire/pop once or twice before it clears. Today, the revs started fluctuating a little bit before the engine died in traffic. Managed to get it restarted and at quite high revs managed to get it off the road.

 

Tried restarting it and the engine just turned over. Occasionally a slight flutter and nothing. Eventually it restarted for a few seconds then died again.

 

So, I've walked home and left it to cool down for an hour before I attempt to get it restarted and back home again.

 

Does this sound like a PTU gone AWOL problem? It's still the original one iirc.

 

Thanks in advance.

....or could it be my MAF?

Sounds more like the MAF. Usually when the PTU packs in thats it. Nothing.

 

Any close by who can lend you both to A, get you home and B, see what it is.

 

Or you could just sell me your now knacked motor.

I'll take it away for a couple of £100. :D :D

There is, but he's not answering the phone. It's litterally 1 mile from my house.

 

I'll go back and have a fiddle with the MAF in a minute. With a bit of luck, it might just be a connector issue (as I've lost the spring clip that holds the loom to the connector).

Just drove it back with no problems at all. I took the nose panel off and the clip didn't feel like it was on quite enough. Fingers crossed anyway. Doesn't explain the occasional pop on warm start up though.

Just pulled clode 43 off the ECU...not sure what that is, will have a hun.

43 is TPS.... I guess I'll give the connectors a clean. Do these **** up occasionally?

sounds like exactly what mine did it was the maf.

Sounds is the MAF heat sensitive like PTUs are?
