I have a 90 with 103K on her and noticed she was suffering from a severe lack of power. Posted symptoms to this group and received great advice. I did some trouble shooting (plugs, wires, air cleaner...), but still no improvement in performance. I took it to the local dealer who informed me that the crankshaft was going. He said it was common with the 90's, something to do with the "key". Quoted a price of about $2100 to fix! Since "top-down" weather is just about over here in the northeast, I'm thinking I'll be saving money over the cold months to have her fixed in the Spring.
3 questions: is this a common problem, does that price sound right, should I get a new engine instead?Thanks in advance for inputs.
