Hi guys,
The car is '94 Aero. A/T
The car ran just fine but juz about a week ago it begin to hesitate
during low throttle (no boost).
Lately it also sputters severely when let off gas to lower speed from
any speed (even from 60 mph it sputters)
On boost, the car is quick as usual, no hesitation.
Noticed one thing strange, normally when let off gas pedal completely
at high speed (> 60 mph), the edu would say 99MPG
But now when the sputtering happened, the EDU would reads 30-50 mpg,
even still at high speed and completely let off gas.
- Tried : new plugs, new DI, FPR check no leakage.
- Did get 6 blinks CEL sometimes, but restart the car CEL disappeared.
Any advice is greatly appreciate! TIA guys!!
