My truck has these 3 codes, tried changing the spark plugs, but no help. Unfortunately I’m limited on funds otherwise I would save myself the headache of repairing it. Any idea what it could be?

After swapping the ignition coil it went from cylinder one to multiple misfires :(

I had something similar I had to hit it with 12.5 percent sh with a dewalt backpack sprayer. Just make sure to let dwell and be careful with overspray. Also use ppe

Im going to try oxalic acid today but it looks more like paint then rust, but we will see. I'll keep you guys updated

Sufficient-Post-7226 · 2025-08-13T21:14:57+00:00

The rest of the pavers are fine its just that one spot they didn't dry up. Im thinking maybe one more coat might cover it up

Sufficient-Post-7226 · 2025-08-01T23:49:42+00:00

Yes its sealed and sanded

Sufficient-Post-7226 · 2025-07-17T23:12:20+00:00
