Engine Light

[Wicked_Lex]

Sorry if anything related has already be posted, but I could'nt find anything specific in the threads. I have a 2000 GS400 with 120K miles. Everything is stock accept for Magnaflow mufflers and SRT intake. I have been experiencing a problem recently when I let up on the gas to approach a stop. Sometimes the engine light comes on and when it does it is like the accelerator goes dead. No matter what force is applied the engine just idles. I shut off the engine, remove positive baterry cable to reset the computer, the engine light goes off and everthing is fine - for awhile. It seems like it happens more often after I have been driving on the highway for awhile and then pull off and drive around town. Has anyone else experience this problem? Is it related to the SRT piggyback? The computer? Fuel pump? Thanks

When the MIL is on, you must check for codes. If the VSC Off indicator is also lit, I would suspect a problem with the throttle position sensor or accelerator position sensor.

it sounds like what happened to my 93 gs300, i had to take off the EGR valve and clean it, after that it worked fine, but it would be best if you went out and found out what codes were comming up though

to narrow the problem down, i suggest you put your stock intake back on and see if that corrects the problem.. my guess would be the srt piggyback as your problem.. with the after intakes being 3" piping, the air mass sensor does not correctly read the air flow.. i had the same problem with my intake.. basically, i wasn't getting enough fuel.. if the intake is the problem, give srt a call or invest in an air fuel controller...GL
