I'm a new member from auburn Indiana. Just got a 94 mark VIII. Currently having a high idle. Car idles around 1100-1300. Have been reading about iac maf, or tps could be there culprit. Now just need to figure out which one is bad. If I unplug the maf it surges low idle like a cam. Plug it in idles back at the same high idle. If I mess with the wires for maf going into the filter box idles will lower and soon as I let up raises again. Sensor doesn't look dirty or bad but could still be a prob. Is it hard to change the iac. In a 2gen?

So I checked for vacation leaks didn't find any lines leaking but did find the seal for intake tube is ripped down one side. So if the throttle body doesn't seal right to the intake tube can this cause my slight high idle. It makes sense to me seeing how maf would say one thing but throttle position sensor could be saying something else than maf. Looking for a second opinion.
