1 - checked that, tps reads .5V @ closed & 4.5V @ open - just like he's supposed to
2 I did change the injectors over from my other engine, and they ran fine with this ECU, so not this...
3. fuel pressure is good.
the idle is still fairly high (like 1500) but if i disconnect the sensor on top of the throttle body (forgot the name of it), the idle drops to almost normal, but won't stay there unless we hold it at WOT . . . then it just sits at 500 til you let off the gas and it dies.
