The last couple days when I've been driving my car ('97 Cobra) around, when I come to a stop it's idling really low compared to what it did when I bought it a couple months ago, it died on me yesterday, and I'm just generally confused. It never used to do any of this except for a little erratic idling with the A/C on.
What it used to do:
When I'd push in the clutch and put it in neutral rolling to a stop, it'd hang around 1100-1200 until I came to a stop, then drop to normal idle. My buddy's '97 does the same thing so I figured that's about normal. When I'd turn on the A/C, it'd idle up and down a little as the compressor engaged/disengaged and when driving I could feel it through the car when it'd kick on. Was thinking that's not really normal tho
What it does now:
When I push in the clutch, it drops to ~8-900 rpms immediately, and idles around 5-600 once I'm stopped. When I turn on the A/C, it'll idle up and down (seen it as low as 3-400 and it'll barely catch itself) and it died on me yesterday while I was stopped with the A/C on.
It just started doing this after I put in new Autolite Platinum plugs and a new PCV valve. The next day, my buddy was telling me that everyone on here swears that you need to run the Copper plugs, could the Platinums be causing the problem? I took off my IAC and it's clean/fairly new, don't know about my TPS, I tried testing it but can't get a reading. Gonna try cleaning the maf next
Any ideas??
