I drive a '99 4runner 3.4l 110k miles. I've been putting gas&oil in my 4runner for the last 2 months. I ride a dirt bike. I always like to put fresh mixed gas in my dirt bike and drain every ride and put it in my 4runner. Now I got a cel which is P0120 tps. I haven't gotten cel for 5 years. I know I'm so stupid for putting mixed gas in my rig because I use '94 premium gas and highest oil quality and didn't want to throw away anywhere. I'm thinking that fuel injectors might be done in the near future? Is my motor done?

sorry for my english. English isn't my first lanuage.

 

Change the tps and you should be good. I don't know if the gas&oil is a good idea but the p0120 wouldn't be caused by fuel problems.

 

I highly doubt it. I've heard folks who run an oil mix like the results. All your doing is lubricating the fuel system, intake valves and upper cylinders. Then again it depends on how much mix your running.

If I were you I would run your dirt bike more often.
