True but he wants to shotgun parts at it. Could be a module or wiring problem as well. Worse case scenario he replaces all physical components and ends up troubleshooting the wiring. Oh well....

I found out the hard way one time.....ordered a very expensive throttle body assembly....installed it....was ok for one day......a come back for me, which I was not happy about(whenever I got one, a big deal was made about it!!!!!!!!!!)......

Further electrical testing, while flexing the wires in the harness to the throttle body, exposed a broken wire/connection inside the insulation....When the engine would flex back/forth a certain way, the harness would move a little and cause an intermittent problem....

But if the guy has the money to shotgun, so be it.....

Oh yeah. We all had one or more of them on our resume. Part os our growing pains.

Ya so it only acted up when below 20 degrees Celsius so i wont know if it worked till next winter lol
But i cant see bad wiring only act up with temperature change... i could be wrong though.
