Hey all, been awhile.
Ive got an issue with my 88 BII auto. (NO CATS)
Runs rougher than hell with much less power. Can only slightly feed the gas to her or it farts and stumbles. It seems to drop a cylinder and run like crap, although when I try a different plug in the wire it has fire. The old plug will be wet like it isnt firing at all though.
Ive tried different plugs, plug wires, new cap, and cleaned up the button with some fine sandpaper but the issue is still there. I start it up without the plug in to blow out the cylinder before trying different plugs too.
I was told it could be a stuck/broken valve, but this truck is only driven in 1st-2nd gear in the woods for getting firewood. (it literally doesnt get driven fast enough to hit 3rd) It doesnt get over revved, hasnt been over revved, and rarely gets run over 20mph in its duties. It probably gets driven 15 miles a year total off road. I wouldnt think Id lose a valve in this manner, but anything is possible I guess. The engine is mint, as it was my daughters ride before she whacked a tree on the drivers A pillar, crushing the firewall and rendering it totaled for road use. Ive used it for firewood for 4 years before this issue started happening.
I have a hunch the injector is fukt on that cylinder, and it isnt getting good (or any) gas spray but have no handy spare at the moment. Could a clogged injector act like what Im explaining?
Quite possibly one of my fuel pumps are toast and its just not getting good flow, but it seems to be mainly this one plug thats acting up. Maybe the timing slipped a little at the dizzy? Dunno, but Im going to look further at it once the back yard dries up. Any suggestions would be great.
Thanks for any replies,
