Hey guys..got a question for ya, someone's gotta know this..
Since I bought my X in January, it's had a miss/hesitation above 4,000 RPM.. I tried the standard fare of replace the air filter, clean the MAF, check for vacuum leaks, etc. It was also suggested to me that it could be the vacuum modulator on the tranny, so I pulled the vacuum hose..and, as i expected, it was clean. I'm running out of ideas. I've run countless bottles of fuel injector cleaner, put Marvel Mystery Oil in about 100mi before an oil change (didnt help this problem but quieted my lifters a bit). It's got new Bosch Platinum +4 plugs and Bosch wires, same as my dad's '92. I think it's been getting progressively worse.. I like my X, but I'm getting really frustrated with it..any suggestions you guys have would be greatly appreciated..
Thanks.
