I have an issue going on with my son's truck. he has a Toyota Tacoma extended cab truck. It has the 22R engine in it with 145k miles.

The problem is once the engine gets hot occassionally, not always..when you get really to come back to idle say at a stop sign, it begins to runs rough. It seems like it might shut off but does'nt.

I have checked all of the vacuum hoses, replaced the fuel, air filters. Replaced the spark plugs and wires, replaced the distributer. I did most of this because it was due a tune-up. I typically do most of my repair work, but this one has me stumped. I cleaned the EGR valve out, checked the exhaust and intake connections, I thought once it might be the sensor in the exhast manifold. But it all checks out.I have replaced the O2 sensor, since it was bad, but the problem still persist.

Anyone have any ideas?  

i havent looked at it at all but does the radiator still have coils between the rows or are they rusted into dust??  

I have a 97 toyota tocoma , with the same problem , I have changed the; 02 sensor ,air filter , pcv valve , changed to higher octane fuel , cleaned the egr valve , and the problem still exists with poor fuel economy to boot, what is a toyota owner to do .  

'94 - When you say it gets hot, do you mean up to running temperature or overheating?

'97 - Have you done plugs yet?  

Hope you have a rusty frame and bring it to toyota they will buy it from you for 150% of its value.
