my little toyota has been acting a little strange lately. it seems to be idling a little high, between 1200-1400 rpm, but not all the time. it's also eating a lot of gas, didn't even get 300k out of the last tank, although i was in 4x abit it should still be better than that. other than those issues it's still running super smooth, no sputtering or anything, turns over right away, decent power etc.

so what do you toyota guru's think? is there something goin on or is it just a part of joining the 300 000k club

i would have to say the 300 000K club but check mass air flow sensor, clean it???

there is a host of reasons why ? ... most common is the o2 sensor or thermo sensor.

I originally was getting 400+ ... then a sharp drop in fuel economy , not even so much in power .. just fuel economy .

compression check soon turned out a burnt valve

Maybe this had to do with an air lock in the system and giving a false temp. to the temp. sensor and temp sensor switch then to comp. and not letting the vehicle complete the cold start, thus keeping idle up to warm engine...concluding in excessive fuel consumption because the "5th" cold start injector is still in operation to richen the mixture to increase temp...and idle high....just a theory???????

c'mon nezzy ur better than that u know the answer ,its ur lead foot.ha jokin but seriously tho id agree with the heat issue. its trikin the puter and with that cold snap yous had(maybe thermostat was stuck, check it out it may be that easy.after all thats what you told hedges and i to do for his.

sounds like a vaccum leak. go buy a can of carb medic. then with truck running, spray the carb medic around the intake, throtle body gaskets etc, and around the injector seals. if you notice a change in idle when doing this you have a vaccum leak.


all of the times i have seen a bad temp sender it caused the truck to run rich, which caused lots of black smoke, and stalling, and 9/10 a check engine light. If there is no black smoke, and no check engine light on, i'd lean towards a vaccum leak.

Im in the same boat with low milage. Built 22re around 300k to a tank,might have something to do with running my boggers at 5psi all the time (to lazzy to air up and down).
