So I do NOT need a new catalytic convertor ... My Del Sol still hesitates and lacks power throught the RPM band, but since its been cold out I noticed something different.
A few weeks ago when the weather was warmer my car would always after a few minutes, when the motor would reach its normal engine temp, (about half way on the temp gauge) hesitate, lack power and get bad gas mileage ... but only after the engine warmed up. After initial start-up it does not do it.
Ever since it has been super cold out I noticed something different ...
During the 20 minute drive to work in the mornings since its been cold, the needle on the temp gauge will barely sneak past the "C" or sometimes almost never move and the car will not have any problems at all. No hesitation or lack of power.
Knowing this now, I came to the conclusion that the cars only runs like crap under load when the motor gets warm ... never when its cold. Which eliminates it being the catalytic convertor.
Facts: Hesitation/lack of power when:
Motor is warm
Throught RPM band
Really bad at low range in the RPM band
Any other thoughts?!?!?! Im stumped.
BTW, my cap/rotor/plugs/wires and fuel filter were all changed and problem still persists ...
