Whats with This

[Black Bart]

I have been trying to help a friend troubleshoot a cold start hesitation on his

2000 Tahoe, he has a Haynes manual that covers 99-03 but the haynes shows

a cable to the throttle body and the friend's Tahoe has a motor driven throttle

body. What gives?

[willieboy]

99-02 was cable driven. I am guessing your friend has an '03-'05 Tahoe, which is drive by wire (motor driven TB).

The motor driven throttle bodies (drive by wire) were used in the a few 2000 trucks/SUV's, more 2001 and even more in 2002. In 2003 they became standard in most all the trucks and SUV's.

So yes, it could have DBW!

The Tahoes with traction control in 2000-02 had drive by wire also.

Thanks to all who replied, I guess its time to find another manual before

we can go any further on troubleshooting, tried cleaning the egr but no

help.

 

Thanks Dave B.
