Just did O2 sensors. Idled fine when I started her up but the idle rose to 1300 when she warmed up. Since the vac gauge reads 16 at this RPM and does not move does this rule out valve problems and leave only Vacuum leaks????
I have a B-303 w/ 1.7rr if you could give me the general area it should be at 1400 - 1600 I will check it when I get home in 2 1/2 hours, if not I will post the results.
Thanks
Ok I got up early before school and stoped by the advanced auto and bought the carb cleaner. I cleaned the IAC and then the TB. It seemed like there was a little change but not really. The car drives fine when ingauged in gear. Once the clutch is pushed in she surges to about 2000 then...
"An engine that whose idle speed cannot be set at 600 RPM with the IAC disconnected has mechanical problems. Vacuum leaks are the #1 suspect in this case. A vacuum gauge will help pinpoint both vacuum leaks and improperly adjusted valves. A sticking valve or one adjusted too tight will cause low...
Hooked a vacuum guage up, no vacuum leaks car still idleing 1600
went through checklist nothing helped, checked tps, checked mass-air, checked iac, nothing's helping, any other ideas, maybe too big an intake, probably not though.
After the head install car idels at 1500 hundred, was ideling a 3000, fixed vaccume leak with new plenum gasket and bought a fuel pressure gauge and timed the car. Any ideas????
