I've got a 1987 Alante with 40k that all of a sudden sounds like its running on 5 or 6 cylinders. Starts up reasonably easy under the circumstances. The exhaust sounds loud as well. Any ideas? Also, how do you pull the codes?

Re: 1987 Alante running problems
Having the ability to pull codes and no service manual is like having the bullets and no gun! If its not plugs and wires then you have either a wiring connector at an injector thats loose or an injector thats failed. With a service manual, you can short out each injector to locate the faulty cylinder. Once located, then you can determine if its a spark plug, wire or injector.
