Loss of power
Hello all, hope someone here can help.
My GTV has been in the garage since last week, after it started to miss-behave just before christmas.
Problem first presented itself as a slight hesitation on acceleration every now and then. This went on for about a week, then suddenly the engine warning light came on, and revs died to idle, with no response from the accelerator. Switched off the engine and restarted; throttle response back to normal, but light still on. Took it the garage, who read fault codes on MAF, and throttle position sensor. First replaced the MAF - problem persisted. Then the throttle position switch - still not sorted. Back at the garage now, who have checked all connections and hoses, and are stumped. Apparently reading some sort of back feed to the ECU, which could be an internal wiring fault, or a fault with the ECU itself. Going to the main dealer in the next couple of days to see if they have any other suggestions.
Obviously neither the independent nor myself really want to put in a new ECU if that's not really at fault.
Anyone had this problem, or any suggestions what else to check?
Any advice greatly appreciated.
