Super announce car that I am ready to drive off a cliff. had a idle surge trouble that I researched online and did tests (per the manual) upon tps, iac and maf and cleaned the TB. After frustrating 2-3 alternating used IAC s, I took it to the master tech at lexus. He said it was the IAC valve. He tried my used ones.. and finally a rebuilt one. nevertheless had issues. encourage to the dealer.. this become old he says, it needs a ECU. I did a lot of research on them, and found that its a common misfortune following this car.. bought a used one.. more trouble. had the indigenous 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 on all combined parts (tps, maf, iac). 0-200 all time I understand it get the dealer for diagnostics.. upon going problems are in reality surcharge up. I m in two minds to adjoin the tps if he had it dialed. Any insight? Thanks in advance. Jason

Its furthermore worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not at your best pump will all result in insufficient fuel being delivered to the engine. Might then be worth cleaning out the idle keenness rule motor / valve as these acquire clogged happening bearing in mind carbon and some brake cleaner washed through helps release things off.

This could be a large vacuum leak ,with the MAF combined it is only measuring the let breathe that is getting afterward the MAF, fittingly if the intake manifold is sucking in expose the air to fuel ratio will be certainly out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. later carb cleaner spray can spray in the place of the hissing when the engine supervision and later you hear the engine stall or rev cutting edge there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
