    New Engine - Sputtering On Acceleration

    SOLVED! It’s unreal, but the shop installed the wrong spark plugs! Gapped to 0.060” instead of 0.045”. I put the OEM plugs and it runs great.

    Wiring Differences 88-90?

    SuperBuick reacted to GnatGoSplat for a topic

    I don't remember there being too much different in the wiring. I had installed a GM Accessories alarm in the '88 and was able to completely go by the wiring diagram and service manual of the '89.
