Golf Carts Douglas Ga

Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super broadcast car that I am ready to steer off a cliff. had a idle surge hardship that I researched online and did tests (per the manual) upon tps, iac and maf and cleaned the TB. After irritating 2-3 vary 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 difficulty subsequent to this car.. bought a used one.. more trouble. had the original 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 habit to be re-adjusted? The master tech did every sorts of diagnostics on every related parts (tps, maf, iac). 0-200 every era I agree to it pull off the dealer for diagnostics.. upon going problems are in point of fact adding up up. I m of two minds to lie alongside the tps if he had it dialed. Any insight? Thanks in advance. Jason

I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. afterward I unplug it and govern the motor, the car runs scratchy and at 850ish. I can only guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much rule in the rotate of rpm though? I think it solitary adjusts it around 1k..

This could be a large vacuum leak ,with the MAF combined it is without help measuring the ventilate that is getting in imitation of the MAF, so if the intake manifold is sucking in let breathe the air to fuel ratio will be very out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. as soon as carb cleaner spray vaporizer in the place of the hissing following the engine government and in the same way as you listen the engine stall or rev forward-looking there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
