Details on Pilot Automatic GTO Wiring and Acceleration Problems!

A rumor has been started on the internet, that automatic equipped GTO’s were having some sort of computer issue that was causing acceleration problems. I spoke with Pontiac today about these concerns, and got to what I feel is the bottom of the issue, so here is the scoop. All GTO’s that have shown up thus far in magazine tests and such were part of the pilot run of about 25 GTO’s. In other words, they are not actual production cars that people will ever buy, instead they are test vehicles which are built for the purpose of showing the media and working out any problems before real production. Due to the all the powertrain and exhaust changes that GM made in converting the Monaro to the GTO, an issue arose concerning the relocation of a wiring harness that among other things was integral to the traction control system. Basically the new location was causing the wiring harness was becoming pinched or damaged in some way, which caused the traction control system to act erratically under hard acceleration. The common malfunction from the wiring issue was that it caused throttle relaxer portion of the three-stage TCS system to kick in too early when the car was floored. This obviously caused the computer to cut power to the engine and hurt acceleration numbers. This problem only affected automatic PILOT GTO’s and has been corrected for all production GTO’s, including the ones already on US soil. To our knowledge, the only magazine that tested a car with the wiring problem according to Pontiac was Pontiac Enthusiast. Again, please remember this does not affect production GTO’s and that it is common to have issues with pilot cars, that is why they make them.
Also on another note, the second shipment of GTO’s has arrived in San Diego, which leaves the total in the states now at over 900!
