Don't know what's wrong with my truck. It was giving lean codes and would not idle. I replaced the intake gaskets, PVC valve, cleaned the IACV, replaced the O-rings, and the injectors. It seems to idle better now but when I put it in drive it idles funny and pours out white smoke from the muffler. So far my truck as not been overheating expect when I'm out of coolant. My radiator does leak. My engine is a SOHC V6 2wd. Please help

I would do a chemical test to check for head gasket leak or cracked head.

In addition to the very good info you've already received, check the engine oil to see if coolant is mixing with the oil. If so the oil will be milky white(ish) in color. Also post the trouble code (number) that you're getting.
