rough idle problem

vladkalika · 11-24-2005, 05:42 AM

Just bought 1989 Supra Turbo (4th one I've owned) with bad exhaust manifold gasket. So I changed it out along with a bunch of old cracked hoses and installed new spark plugs.

Now it idles extremely rough, wants to stall, and from the tailpipe it sounds like it's missing (definitely not smooth purr it used to have). It also seems to run hot; temp gauge shows normal but underhood temp especially around turbo is blistering hot.

I double-checked ignition wires and all the sensors/plugs. Any suggestions what it might be?
