Had the starter replaced on my GS400 this week by a local mechanic.After getting home I noticed the CEL was on,the VSC and VSC Off indicators are on(hitting the VSC switch does nothing) and the engine now vibrates..With the hood up I can see the engine vibrating where as before it never moved.It also doesnt have the snap acceleration like it usually does.When idling,it seems to be sputtering.Im thinking off hand the new gaskets aren seated properly.Ill be taking it back to the shop tomorrow but was wondering if anyone has any ideas of what went wrong.Thanx in advance.

sounds like a vacuum leak... most likely a hose left unplugged...

could also be a sensor unplugged...

intake gaskets are a possibility, but honestly kinda hard to screw up...

Thanks for the reply..It does feel like something isnt sealed and no pressure is being built up.So its probably something simple then??Anything major he could have screwed up??

UPDATE..Codes..
P0300
P0303
P1310

Time to search..

VVT-i

P0300 and 303 is misfire on cylinder #3,but I don't know from the top of my head about the P1310. He may left the #3 injector unplug. If you open the hood #3 is located on the driver side not too far from the oil filler cap very easy to get to, just look for the blue connector(injector).

Thanx..If it is the second from the front it does seem to not be in all the way..Just drove the car so the engine is still a tad warm and my STB is in the way..Gonna let it cool dow a little and report back..Thanx..

BTW..P1310 Igniter Circuit - No. 2.

UPDATE..Checked that plug(it was loose) and all is good now..The rough idle is gone ,power is back but the CEL,VSC and VSC OFF lights are still on..Is there a reset or will it correct itself in time..Thanx again

scantool should be able to do a reset... without looking it up, if all is fixed, then the light should turn off after usually 2 drive cycles that the problem doesn't occur...

some codes do not turn off this way and must be reset though...
