Lost power to engine


Check make sure all plugs are firing. Sounds like what my 93 Rodeo was doing-Idled okay but very rough when in gear. Turns out only 5 out of 6 plugs were firing due to a defective ignition module- 100 bucks later it works fine.

Hope this helps.

Missing


Sounds like a load miss. Chk plug wires for deterioration and or cross firing. Wires should not cross over each other. Worn plugs load wires causing increase spark out put increasing cross firing potential

I just had the same issue with my 88 xlt w/351 W it wound up being the MAP sensor and the timing. I would check both of these and see if it solves your issue.
