i have a '99 GS 300 with SRT intake and am having an issue with engine / power that needs to be resolved.

when you hit the gas it takes forever to pick up any speed (from a standing start) and its goes to 5 or 6,000 rpm before it shifts. Very very slowly it will pick up speed but just runs very very slugishly.

when on the highway you have to floor it to get up to 70 -80 mph.

well today, i am driving on a slow street and the car just totally loses any power and the check engine light comes on and the VSC power on/off button (both) comes on.
I hit the accelerator but it does nothing.

I gently pull over to the side and shut car off and it restarts but same thing - no power.

I try again and the same engine lights are on but at least the car moves when I hit the gas.

FYI, I changed the MAF sensor 1 week ago hoping it would fix my engine problem - but I still have the same issue.

WTF is my engine issue?

Thanks in advance for your help.

possible TPS ..throttle postion sensor or something like that

 

would the TPS cause the check engine and VSC lights to come on?

Ted

 

from everything ive read yes

but you know what so would an open circuit in the MAF sensor

make sure that connection is all tight

make sure you put it in the right way too

but if you put it in backwards the car wouldnt even start

contact Carson for the Part i think its under $100

search for TPS seems like you have the symptoms

 

I had twice this happened in the past two years. Other members suggest me to check the oil cap and make sure it is tight. To fix the problem, you need to disconnect the power of the battery (reset the engine light), then you connect it back and should be back to normal. However, I have no idea why it was happened.

Hope this help.

KEV:

I don;t think that this is my problem b/c I did disconnect the battery and still have the same issue.

ITS THE TPS.. Same thing happened to me a couple of months ago.. Changed it and problem disappeared. Good luck !

 

Andy:

where did you go to get the TPS fixed?

dealerships in CT don;t even want to seeme b/c "its a modified Lexus".

such punks.

help a desperate CL member out?
