He tried my used ones.. and finally a rebuilt one. nevertheless had issues. incite to the dealer.. this get older he says, it needs a ECU. I did a lot of research upon them, and found that its a common problem later than this car.. bought a used one.. more trouble. had the native one rebuilt by a specialist.. and that s where I am at now.. Put it in tonight and the car idles at 2k rpm. Does the TPS compulsion to be re-adjusted? The master tech did all sorts of diagnostics upon all united parts (tps, maf, iac). 0-200 every mature I resign yourself to it realize the dealer for diagnostics.. upon going problems are in fact tally up. I m hesitant to be adjacent to the tps if he had it dialed. Any insight? Thanks in advance. Jason
