Once a week or so my car will do the following - 9 times out of 10 it will be within the first couple of minutes of the car being driven (I never drive the car cold)

1) I'll go to move off and when I press the throttle it will choke up and start to stall

2) When I let the throttle off it springs back to idle perfectly

3) I press the throttle on a bit and it goes to die again.

4) I turn the car off, switch the immobilser on, wait a minute or so...

5) I turn the car back on, she fires up, and no more probs for a good week if not two - pulls fkn hard, no other issues at all...

I'm just waiting for that 1% chance that it happens when I really NEED to move and I die a terrible death.

Any thoughts?

What ecu?

Have u done all the basics. Service parts, fule filter air filter spark plugs ?

Have u ever set the tps position?

Remapped stock ecu (definitely seems like it could be an ecu related problem given that it is so infrequent)

Car had every filter and plugs and all fluids replaced in November last year, car has done about 8000 kms since then. 4000 being from Sydney to Perth the day after this work was done.

Never set the TPS up. Was going to mention TPS actually. It really just seems like the car doesn't understand the message sent to the tps sometimes hey. Like its sending the opposite message?

Car had a coupla dyno runs last week - do they do anything to the tps on a dyno run? As opposed to a full tune?

      Nah that is not actually a lot. Just painting my GTR frontend and the little bits to make sideskirts/nismo flare pieces work correctly/fit on the sedan/mount up correctly came to about $7000. Is it a lot? Sure. None of this is economical. Economy would be shelling the car and buying a 2010 Corolla to commute in. The perspective of all of this is different.

      I don't see any issues here. I've been saying all along this is a big job, the price reflects that.  When the car comes back perfect I'm sure it will feel like money well spent.

      Remember, take original quote. Double it. Then add a bit more. It's how any project goes.

      So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
