on my crank pulley my ignition marks were cut wrong.. so after rebuild i had to guestamate what to time my car at. well i finally baught another pulley and gettin ready to time it. ive read that the ecu can pull about 10* out of timing. and there was another thread of a guy claiming to be running 25* and people telling him bs. well my ingnition timming was around 25* i say this cause it was beond the last mark. well when i turned it back to retard it the car started to idle really really low like 300rpm i think. well i plugged in the tps sensor and it idled it. was this from the ecu pulling the 10*? also to add about the other guy in 25* the car runs liek crap no torque or power till over 4k.
