| I have 1990 and it seems extremely hesitant when accelerating. Turbo gauge stays in the lower yellow and upper white sections. Does seem to have much power. Not sure what to do. |

| have you checked turbo shaft play? should have almost zero side to side movement and zero in/out movement. also check your spark plugs for proper part number and gap. when is the last time the fuel filter was changed? check the vacuum reference hose on fuel pressure regulator. is there a foul odor from the exhaust? take the car for a winded drive and look under car to see if cat is glowing red. |
