Firefox13

Sorry all if this has been brought up before. I’ve looked but haven’t felt like anything was quite in line. My 95 5.8L has 90000 original miles and was meticulously maintained. The one issue it has is a shudder at idle. Like the truck is getting the chills. I don’t have a tach so I’m not sure how low the rpms are dipping. The shudder is worse and much more consistent with the AC running. Any ideas what could be causing this? Thanks I’m advance.

Have you looked at the IAC - Idle Air Control?

Edit: Not sure if that year has a TPS - Throttle Position Sensor but might check it as well.

I’ll take a look. Thank you.
