On a related note I just changed plugs on my 94. I bought it awhile ago, but had it in hiding from the wife for longer than normal. I changed plugs for the first time on this car and bought a few different sets. I pulled out some NGK Triex5 I think. I think an older plug of there. It was running fine but I am doing all the maintenance so I know where it is. I replaced these plugs with NGK Iridium plugs and ran fine for a few days then noticed a stumble turning into my driveway. Seems to stumble at times below 2000 rpm, more pronounced at 1000 to 1500. Idle didn't seem quite as smooth but after reading this analysis I might first change plugs, but also check pressure and fpr.
