First of all, wanted to introduce myself. Today I brought a 1992 v6 4runner with 180,000 miles, I was told it had some minor issues but I got it at a good price. Okay, so here is what it does.

Problem #1: It has a loss of power, mainly on takeoff(Hesitation) but it seems it should do far better up a hill than it does as well.

Problem #2: Difficult to start, when it does get started I have to keep it running because if I shut it off for more than 5 minutes afterwards, I have to wait for the engine to cool completely before it will start again.

What has been done: Previous owner reports doing the following to correct the problem(s).

New MAF Sensor
New Plugs
New Plug Wires
New fuel filter
New Battery
Compression test tested OK.

All of these fixes did not solve the problems outlined above. The previous owner as well as some mechanically inclined friends of mine both suspect some type of sensor. Any responses and/or advice would be greatly appreciated.

Forgot to add this question, could a malfunctioning EGR valve cause any of these problems? If so, how can I check it?
