Built TT - needs help
My car has been at the shop for over 3 months trying to figure out an issue that came up back at the beginning of Oct.
Here is what my car is doing: I have the e01 boost controller, greddy TT with built sleeved engine running 17 psi with the UTEC (the stock ECU was reflashed by technosquare and the idle bumped up to 1000 for the jwt cams, etc.). The car will start and idle but when you push the gas down there is no reaction from the car (it may rev up to 12-1300 rpms but nothing further). It's as if the car doesn't recognize the peddle being pushed down. This happened as a was casually driving home one day and the car sorta sputtered then wouldn't move.
The shop here initially thought it was a UTEC issue (tested/replaced), then a TPS sensor issue either at the throttle body or peddle (throttle body with TPS replaced), then something called an IPDM-ER unit (replaced) or something (a unit mounted on the firewall that relays computer signals?), then they had an electrician look at it to see if something/relay could be bypassed to get the car to work. Well, after the electrician looked it over the car would run and react to the peddle. The problem was that as soon as you shut the car off, after driving the car for a while, the car would revert back to the same old issue of not recognizing the throttle/peddle being pushed down (they said it had something to do with the heat after the car had been run which was causing something electrical to shut off). After the car cooled down, it would run fine again during their tests until, again, the car was shut off. Once it was turned back on when it was warm, the car would revert back to the issue. Now, I guess they think its my stock ECU and something in it is fried. I'm told that the ECU is no good.
So, I'm trying to now find a used stock ECU for my 03 Z. I'll then have to send it to Technosquare to get the reflash again.....I'm wondering if they will cut me a break on the cost since I've already gone through them for the reflash? Anyway, I wanted to check here to see if anyone had possible ideas on what the issue could be with my car? Possibly solutions, etc. Any help would be appreciated since I haven't had my car for about 3 1/2 months because of this issue. Thanks guys.

If you got a SES light, what are the codes?If you hace a P0605 its the ECU..This code is a P0123 APP sensor Voltage or something like that if I recall...
