Throwing parts at it? Spark plugs are sometimes the simplest fault,
and cost $4.50CND for all four and take me about 10 mins tops to change. AS for the cold air intake, I will not argue with you on that one. I know under almost every application, an CAI has been known to add a little without affecting mileage or life of engine. (The down side is noise.) But like I said, I will not argue with you on it as not all add-ons work on every application. Prime example, throtle body spacers, I done not believe they will do anything, but others beleive it does. Now, to the engine codes. The only codes I had when I checked it a few months ago was A/C clutch sensor. I never use the A/C, so this is no big issue. I think I will take a closer look at the MAP and O2 sensors as mentioned in one of the other postings. There has not been any error codes displayed regarding then, but I will have then checked when I bring the car into my neighbour's shops this following week. Mike "Daniel J.

OK, but I have to assume you would've posted "95 Neon running rich" a few months ago had the problem been there, so why don't you check the codes *again* and let us know what you find *now*? > but I will have then checked when I bring the car into my neighbour's > shops this following week.
