i dont know what you did, but you did do something... i removed mine, and my power steering at the same time.. and ive removed my front and rear bumpers and all my airbag sensors
too.. but i aint never had this occour on mine...
have you tried just pulling the connectors out of the ecu and leaving them out for about 5 mins to reset everything??? i had to do that recently to get mine out of closed loop mode..
oh, and rocket your a genius guy ... my car was pulsing or surging due to momentary lean out cuase my hot start solinoid was shitting the bed slowly... i retimed it to the 12*BTDC and removed the solinoid completely.. and poof ...shits running like a scalded dog again.. and i thought i covered everything fuel and spark related, until you said momentary lean..
and it all clicked in my head.... thanx again...Joe
