ok here goes! (300zx TT auto jap) egr bypass, plenum bypass, dett bypass, A/C removed, dump valves fitted, code 55.

 

car idles fine when cold!:)

car idles a little up & down when warm!

car is fine in drive (9 out of 10 times)

car stalls when in reverse??:(

 

help please ???

bump!

send jeff TT a pm he will help you out :)

will do..cheers

Didn't you just have your engine out? Wondering why you did a det-bypass in that case?

put a new dett sensor in but still gave code 54?(dett code) so bypassed it & code whent so the new sensor must have been faulty even though it was new!! not taking it all apart again lol

Did you replace the small det sensor loom?

yeah it came with new one

That's odd. The it wouldn't have been the det sensor. I would have traced it and got it sorted. Probably crappy wiring post sensor. Sorry, just a thought.

 

What's your TPS set to voltage-wise?

it cant be the loom cos i have put the resistor in the loom connector & that has cleared the fault, the tps is bang on as dannzx checked it on the conzult, think i got a duff 02 sensor but that wouldnt cause it to stall in gear would it?

No, I have an o2 sensor that's out. It'll just run a little more rich. I have 2 new ones for mine. You're welcome to have the one that works...whenever Jimmer can spare a morning. :)

 

Mind you, yours is an auto. So might be something completely different.

have pm'd jeff so he might shed some light! me & dannzx will be working on it tomorrow, & i will take you up on the o2 offer thank you! could be netural switch but sure that was working!! will check again..

wasnt a proper 300zx dett sensor though to be honest although it was advertised as one and a lot cheaper.:rolleyes:

54 is an auto box code.not the det sensor.itr refers to the communication link between the engine and box ecu.
