Just installed a TSP 231/237 cam and heads. Under hard accelerations I get an SES slight, and the code is High TPS voltage. Going down the road at a normal pace it is fine.

Any thoughts??

I had the computer tuned by TSP already for my mods.... It is a tune problem? Or something I can do here?

Also the car at start up idles at 1350rpm and when put into gear is at 1000rpm and it also has some cam surge..


Mods are listed in my sig.


Thanks

Have a shop check the tps signal voltage at idle and at WOT (key on, engine off)...

Idle should be around .45, WOT should be no more than 4.6 or the SES will come on.

I think they can use Auto Tap to check it. We have a Genesis tool here at school that will read it I believe.

Later,
Mike

ps. The car sounded great Thursday night!

Yes, I think the TPS > 4.8 for some period (I saw
minutes, posted, but that seems large) will set the
code. Check the TB bumpstop, that the blade is
no more than dead center when full open; that
being the case check TPS electrical output and
if necessary, slot the mounting holes & rotate
for something below 4.7V full open voltage.
