Who In the Nor Cal area is good at dialing in these S4Fc's , I have an annoying Idle issue that I cant solve, Been through all the suspects, air flow meter, TPS, vacuum leaks, solenoids, is there someone or a shop that is reasonable that can dial one of these cars in ? Cause I realy want to go out and drive this thing.

Ok heres more info. At idle the rear rotor is not contributing to the running of the engine, meaning I can pull the lead plug for the rear and the idle condidtion does not change, I have 110 75 105 psi on the rear rotor compression wise, To me it seems like the rear rotor is not getting any fuel, because it has spark. I've checked all the regular suspects, Where should I got next. This Motor has 30 miles on it as of today, But it does fluctuate it will run smooth then it will miss and run only on the front rotor. so Crank angle sensor ??? or what ?

the difference between chambers is out of spec. test it again. do you have stuck side seal? How did you clearance them? Did you build the engine?

The motor was built by Rotary performance in Garland Texas.

is the injector clicking? is the injector getting signal from ecu?

after a rebuild sometimes it take time for things to seat properly...maybe thats your problem? Did you email rotary performance regarding how they wanted you to break in the motor?

Yeah they told me light throttle for the first 250 miles , change the oil and then light to mid throttle for the next 250, then I can go full boost and rock and roll, But I have to get the thing to run rite before I got out and drive it, I will check the injectors, It could be that but being that the wiring is soo dificult to get to how do you test it .

To check for voltage being sent to the injectors refer to the link below page 32. Pin 3c,3e,3f,3h of the ECU are the ones you would need to test. Clicking of the injectors could be done with a tube or stethescope although the secondaries are easy to access while the primaries might not.

Yeah all the injectors are clicking, Now I think I have to look at the fuel side of the equasion and see just how much pressure i'm producing and see if the fuel system is the culprit.low fuel fressure would cause the thing to go lean ..

No I wondering , what would these cars run like if the timing was 180 degrees out ? Would they rut at all or would they run realy bad , mis stumble and hunt for fuel ? This motor was preassembled when It arrived at my house, and i'm wondering if the timimg could be that far off. As it is the only thing I have not checked this far.
