i had one of those cars which i bought cheap because it wasn't running well.it was necessary to richen the mixture to get it to start and then it ran at 1200rpm.after i bought it i replaced the 10 amp fuse in the top of the overvoltage protect relay and all was well.with that fuse blown[these cars tended to blow that fuse when being jumped because of dead batt]you have no power to the main fuel injection which also runs the auto idle valve[this valve requires power to close it down].do you remember the audi unintended acceleration in 1985-86,they used the same vdo valves.all the euros changed to a valve that remained closed until powered up for reasons of liability the following year. anyway check the fuse if you need more help call me. david poole european performance dallas tx.214-9567007.
