as long as im checking it right it is NOT losing power, could it have to do with going into closed loop? and can you keep from going into closed loop.

Hose has already been replaced, but yes it is the same type of problem just alot worse. thanks

When i said it lost all power i should have said the engine lost power, i checked voltage at several points, runninig and not, and it seems to all be good, always above 12v and over 13v when running at the battery.

Hello i have a es300 with a build date of 9/95 it does have an OBDII port so i believe its actually an 96 model year. it was runninig great then all of a sudden lost all power, it will idle but if you give it gas it revs up a little and spudders and dies, it never really revs up completely. when you first start it it runs great for about half a block. when i check the codes at first start up when its running good theres no codes, after i let it runn for a minute or two and it starts running bad the check engine light comes on but when i go to check the codes it says no communication, check cables and recheck after doing it a couple times just to make sure it wasn't me or the scanner, got the same results. it has 200,000 new timming belt from dealer at 106,000 plugs, wires, air , and fuel all good PLEASE ANY HELP WOULD BE GREAT
