Helping a friend out with his car, and it seems that about a week ago it started dying randomly, and having difficulty restarting.

I believe it only does this (or at least more often) once the car is up to full temp. as it starts and runs perfect when cold.

Plugs were replaced, and a new set of coils were tested, to rule out the ignition, or that portion of it, but what else could be causing something like this? I ran the car with EvoScan on, and the ECT sensor is returning a good value, and constant, so it isn't that, the o2 sensor seems to be responding well, the tps and iscv seem to be working just fine, where else should I look? Thanks.

 

clean out your maf and iscv if you haven't. also make sure you check if you have a boost leak.

 

did you try only running it on open loop?

 

Er, shoulda added some stuff: It's an SD car, so no MAF.

And no, haven't tried the open loop yet.

 

is the map sensor all good?

 

I am the poor soul with the broken car.

Map sensor is one of the items we will swap over from FORESAKEN's running vehicle to mine for testing.

 

hmmm what where the AFR's looking like when this happens? did you check the fuel pump at all? its gotta be something stupid

 

The owner doesn't feel that gauges are necessary, so AFR is out

 

No, the owner doesnt want a ton of clutter on a DD, with gauges blocking the purdy views of Seattle raindrops or the speedo/Taco.

 

Andrew felt making a new thread would be more accurate than updating his first thread....

Please take a look at the log posted here and if you have any insight I would appreciate your input!
