lokking for advice

I have a 94 toyo pickup and I it started idling high up to 2000 rpm at stop lights, it idles normally at 500 rpm. I noticed white smoke coming from the exhast also, the white smoke goes away after awhile. After this I changed the plugs, wires, distributor cap and rotor; it did not fix the problem. Can someone give me advice on what to do. Also while idling and almost warm it idles from 500 to 2000 it's never done that before.

Is your coolant level dropping? How's your fuel economy? Do you have any codes? What did the old spark plugs look like?

I would do the following:

1)Place a napkin/paper towel over the tailpipe for a few minutes and smell it or see it for coolant residue
2)Perform an cooling system compression check
3)Perform an engine compression check
4)Perform a leak down test
5)Perform a fluid analysis test by buying a fluid analysis kit for $15-20 at any local Caterpillar dealer or any heavy duty repair shop that repairs bulldozers,cats,backhoes,big rigs & more.
6)There is a headgasket recall on most of the V6 engines used in Toyota trucks & 4-Runners,see below

The dealership will give a free rental car for a day or two and replace other routing maintenance parts and only bill you for those parts.The headgasket & it's labour is of course free.
