Hello, I'm new!
just here to ask a few questions. My dad baught a 99 cadillac STS. The engine does not turn over on the first try a lot of the times when the engine is Warm, and when it does, when the engine is idling, I can feel the engine shake (RPMS are approx 1000 RPM) Now, other than the spark plugs and wires (I will replace these shortly), could there be any other issues that I may want to look at? |

some starters get hot from the heat off the manifolds and i seen fixes ranging from replacing the starter to installing a heat shield. if yours turns over once it cools, the issue is probably among these. the engine idle .. plugs, wires, idle controller, carbon build up in intake throttle, vacuum leaks, water in gas, timing, injectors, O2 sensors, etc ...

is there a screw that I can adjust the idle speed? I will also take a look at the throttle body, IAC valve for carbon buildup / garbage.
My own vehicle, the idle speed is controlled by the ECU and cannot be changed / altered w/o reporgramming. Thanks for your help . |
RE: New to forum
no screw. i believe that the idle is regulated by the air control valve
too detailed for me w/o a manual. may look like this one: [IMG]local://upfiles/2893/AEDA86E09DC64D65BEF37674241F0F4C.jpg[/IMG] |
