designed, or there could be an issue...checked my

engines....feels like there is no rev out of this
motor, feels dead until I go on the highway...help

for the porshe.... The reason the temp gauge goes down when you are moving is because there is air moving through and the fan kicks on. check your anti freeze and if that's is ok... try replacing your thermostat.

Thanks Mark already done that....thanks for getting back to me....what about my other questions what do you think....


Recheck your marks when at TDC. Also, the belt tensioner may need new gaskets. An oil leak here can cause timing problems. The fan should be kicking on sooner, so also check or replace the fan switch. Performance Products in Calif offers a lower temperature switch.


The front electric fan....where is the fan switch on my car...still new at it finding where all switches and other parts are and called....lol


Try looking at the rear of the radiator on the top drivers side. Screws in and usually has 2 or 3 prongs. 928's are notorious to work on, you probably will have to remove some of the intake duct to see the switch.


Thank You Mark


MTA, the reason she's sluggish at takeoff, is because of the second gear starts that the auto's do, you can buy a cheap kickdown cable that will allow you to take off in first.
