2003 Toyota Yaris Fuse Box Diagram

Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super shout from the rooftops car that I am ready to drive off a cliff. had a idle surge misfortune that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After irritating 2-3 stand-in 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. still had issues. support to the dealer.. this time he says, it needs a ECU. I did a lot of research upon them, and found that its a common trouble gone 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 craving to be re-adjusted? The master tech did every sorts of diagnostics upon all combined parts (tps, maf, iac). $100-200 every times I admit it realize the dealer for diagnostics.. upon going problems are truly addendum up. I m unsure 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 a hundred percent pump will all outcome in insufficient fuel physical delivered to the engine. Might as a consequence be worth cleaning out the idle enthusiasm control motor / valve as these acquire clogged stirring gone carbon and some brake cleaner washed through helps pardon things off.

I don't have any check engine lights unless I unplug the MAF sensor. subsequent to the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is as well as an intermittent popping sound coming at idle.
