Need everyone’s help.
Couple weeks ago my ‘98 LC started shanking at idle and low rpm and CEL came on. Was an hour from home so I limped it to the closest shop that was open on Sunday, CEL light flashing on and off on the way. Noticed some faint ticking too near the end of my ride, about 12 miles.
Small mom and pop shop in a guys yard, got the codes checked. Misfire cylinder 8 was the only code. Left it with them for a couple days and they said they checked everything they knew would cause a misfire and said the plugs and coils were working correctly but the misfire code would jump to different cylinders. They said compression was good and came to the conclusion it was something electrical but I needed to take it to a better equipped shop to properly diagnose.
Get it towed to shop 2. They get working on it today and are having trouble as well. They say that the misfire code is showing up on different cylinders as well (randomly) but they say that there is no compression on #8. They know I did a timing belt/water pump job ~3,000 miles prior to this incident and say that the belt didn’t jump. They think it’s a bent rod/valve or broken cam. Quoted $4,700 if it’s a total rebuild but said it could be less if they get into it and it’s the camshaft not the valves/rods. I asked about the cost of replacing the engine and he said it would probably be cheaper than the $4,700 quote but would have to get back to me with a price.
Haven’t heard back yet and would like to get everyone’s opinion. Part of me still thinks it’s a wire or connection somewhere gone bad because it was running perfectly before it started shaking and I’m not sure why multiple cylinders would be getting misfire codes if just 1 was down on compression. Thanks for reading.
