So, as some of you know I have spent the past few months rebuilding my new ti (1996 California) which has 303,000 miles. After finishing the assembly and changing all the fluids, I started it up to find that the motor runs beautifully when I am giving it gas. But when it warms up, the idle goes up almost 700rpm and then raises and drops from there about 300rpm both ways... It almost sounds like it is shifting threw the gears.  I know the gas is a 50/50 mix with 1 year old gas/new chevron and a bottle of techron. So maybe the gas is causing issues??? Also the reason I rebuilt it was because it overheated and warped the head. Well after 10+ minutes, It starts to heat up and stay hot. Not red zone hot but close... Could these problems be linked or do I have two seperate issues? Any advise as far as checking specific parts before I just but new (ex: radiator) __________________

Did you change the t-stat? Sounds like a sticking t-stat or the water pump might be junk.
Until you get it in a normal operating temp you risk blowing it again.
The erratic idle is usually the idle control valve being dirty. This is the least of your issues. The I-4 motors are very sensitive to over-heating so take car of that first. | | | | | 02-02-2012, 05:52 PM | #3 | | Senior Member Join Date: Apr 2007 Location: Santa Maria, CA Posts: 277 |
