Hey everyone! Back with a couple questions about my old s10. I bought it about a year ago for $1000. 5 Speed/Ext Cab/250k miles. Since then I've replaced a horn fuse, wipers, front brakes/rotors/calipers and wheel bearings, fuel filter, tires, oil pressure sending unit, some vacuum lines (but probably not enough), etc. It still has no A/C, a bad EGR, some vacuum leak somewhere, a worn carrier bearing, worn differential, worn rear brakes, worn steering box, poor alignment, the list goes on. I've decided it's not worth it to try and fix everything wrong with it and just fix major things as they come up.
Well in the past month some major stuff has come up. About 3 weeks ago I went to start the truck, only heard a solenoid click. No crank. I've found that by turning the key repeatedly it will always catch eventually, after 1-10 turns. Seems to only happen if the trucks been on within the last hour (roughly). I can't figure why it's willing to catch and start fine, but only after several attempts, and was wondering if anyone had theories on that. I'd rather not replace the starter and find it was some other weird part going bad.
I've also been noticing a strange phenomenon, where when I take a gradual turn to the right at high speeds the rear right wheel squeaks constantly, like the brake is dragging. I feel like this may be because the diff is so worn that there's excess endplay and the drums are in fact contacting the side of the shoes, but have no idea. I do suspect my rear brakes are worn almost out, but that shouldn't make it squeak when turning (I don't think).
Most seriously, today I think I lost power on a cylinder, or worse I might have timing/valve problems. I was on the highway and got pissed at a guy so I put it to the floor (a futile effort in a 2.2 but whatever). I hit whatever 85+ speed was possible (speedometer ends there), I'd guess 90-95. Probably the fastest it's ever gone. All of a sudden I felt a vibration that I initially thought was bumps in the highway, but then I noticed the truck was even weaker than normal uphill. Once I came to a stop later it was idling very rough, and the whole damn truck shakes when launching from a stop. I got where I was going and parked it, then got back in and drove home with the same symptoms.
The exhaust sounds different, its got like a puff sound to it, and I smell what I think is unburned gas. So I figure this could either be plugs/wires (unlikely, I think they only have 50k on them), one of the coil packs, the ignition control module, or engine control module (because maybe I hit the governed speed limiter and the ECM messed up after that ???). Or maybe I jumped time or something. Which would suck. I also considered the EGR, because I know for a fact it's bad, but I don't think so because it's been just as broken for a year and given me little trouble.
Here's how the exhaust sounds:
And the engine revving:
I'm thinking about starting by spark testing at each plug and going from there. But the exhaust sound almost doesn't seem congruous with a misfire, it almost sounds like timing/valve issues. That could be a totally wrong assessment, I'm an amateur, but just a thought.
Anyway, if anyone has any thoughts or advice they'd like to share about any of the issues, I'd greatly appreciate it. Thanks!
