Car has been running rough with backfiring on acceleration. On the highway, runs o.k. (definite loss of H.P. though) Ocassionally losses idle and stalls when not in gear. Could trace problem back to blocked Cats, which are now not an issue. Wondering if loss of back pressure causing all my problems. (New exhaust is 2nd on list of repairs unless I learn otherwise) Car sounds like it's out of time. I didn't want to start adjusting the timing until I know all my sensors check out. Car gives me an intermittant check engine light and code 34, whether present or not car runs the same. I can't find the MAP sensor, I'm going crazy looking for it to test it. Car is stock L98, plugs and wires are two years old, IAC O.K., TPS O.K. no obvious vacuum leaks, new O2 sensor. Alternator now on it's way out giving me up to 18 volts on my dashboard gage. This is a very new problem, I don't think they are related.
