I have a 93' 4x4 pickup with a 22re engine. I'ts never given me any grief until this winter it would not start when it was cold. It would fire on either but would stall right away. I put some dry gas in it but it kept happening. now the weather is warmer and it starts fine but idles rough and stalls when I slow down. I also noticed the exhaust smoke is black at times usually when idling. And then yesterday my heater started blowing cold air. turns out the radiator was pretty much empty and when I checked the compression I got 90-100-105-95. It is sitting in my garage now and I'm wondering if this is the end at 127,00 miles. any help would be appreciated. this is my first toyota and unlike my chevy's I don't have any practice working on it.

I don't think the truck is dead.

The first thing I would check is the vaccum lines. The stalling at idle makes me think you may have a vaccum leak. Also, make sure the oil cap is on tight, it is a source of vaccum leaks.

Clean the googe out of the throttle body with some TB cleaner. The TB can get pretty dirty, and that interferes with idling and maybe starting.

The black smoke at idle is too rich a fuel mixture. Check for engine codes as described in the FSM on the sticky.

No starting in cold weather could be the cold start injector. Check the FSM on how to troubleshoot cold starting.

It could be that finding and fixing a vaccum leak will cure your problems. If the hoses are the orginals, you may just want to replace all of them for peace of mind. NAPA usually sells lengths of hose in various diameters. When I did my hoses, I did them in the NAPA parking lot, and I did have to go back inside for more hose and different sizes.

Don't give up, Toyotas are tough little rascals, they just have some idiosyncracies.
