throttle adjustment

[crstfr]

Hi All

I have a MY99 C2 cab. I noticed that I have a little slack on the trottle cable. When i put my finger an the cable where it attaches to the trottle body it depress about 1/4" Is this normal? I am wondering if this is related to the hesitation jerky motion I have mentioned on another post. I plan to look into the trottle body this evening How can I tell if it is opening fully? and how can I make adjustments if necessary?

Thanks

thereshould be a small amount of slack when off throttle. but if you get someone to press the pedal as you watch at the rear you will see if it reaches full throttle without binding on the butterfly too. i dont think this will be linked to your jerky motion?

Hook up your scanner and look at the throttle position when your gas pedal is depressed all the way. If it is less than 100%. remove cable connection and twist the cable 1 turn and reconnect. Do this until you have 100% at WOT.

This assumes that nothing is blocking your pedal from reaching the floor.

Hi I just had my wife depress the gas peddle and the butterfly does not open all the way. What is ment by remove the cable connection (is this the snapin black piece in the housing) Do i just use a screwdriver it push it back. Should it be turned clockwise or anticlockwise. I dont want to break anything. Track day on tuesday!!

thanks

You can get the cable off by operating the throttle by hand and lifting the cable out. Disconnect the end of the cable from the throttlebody. Twist it around once and put it back on make sure it does not untwist.
