| 90 300E serious miss problem - help
OK, so I replaced plugs, cap, rotor, wires and the miss persists. Cylinder 3 appears to be dead. It is getting fuel and spark, but compression is zip, so I assume since this problem went from a minor intermittant rough idle that cleared up to a full time miss that doesn't, that a valve is probably stuck open. May be a piece of carbon. Rebuilt heads look like $940 plus shipping if I reuse my cam/lifters/rockers, $400 to $500 of that being a core charge, so ~$500 to fix.
Before I go that route, what other options might be available? I remember seeing something about a product that can clean the carbon out? Anyone know about that ? Other options? Not sure if I have a local shop that could do a refurb, or if it would even be worth it.
All input appreciated....especially if you have already been through this one.... |
