VSC TRAC, TRAC OFF, CHECK ENGINE lights
Having problems with acceleration from stop and on highway with my 2001 4 runner. The truck would hesitate and stumble slightly as I accelerated. Changed air filter, fuel filter, and put injection cleaner in tank. On the highway as I accelerated to pass a car had a lack of power and check engine , VSC TRAC, and TRAC OFF lights all came on. Truck still had no power, hesitated, and stumbled during acceleration. I was dropping it off to get some paint done so I did not pull the code. It has 84,000 mi and trans. Fluid is full. Any ideas will be appreciated thank you.

try to check your fuel injector, ignition coil or it could be that your toyota oxygen sensor gone bad and it needs a replacement. try also looking for some loose connections or cross wired.. good luck..

Engine Lights
You've probably already fixed this by now but I've had the same lights come on twice. First time was a evap canister and the 2nd was a Fuel/Air Ratio sensor, basically a fancy O2 sensor but required for California spec emmissions. It also cost twice as much of course. Install is a snap for the sensor, the canister I had the dealer do it.

Engine, VSC Trac, Trac Off warning lights
Bought my 2002 4Runner (2WD) a year ago this week and have had no problems at all, what a cool truck!
A couple of days ago was driving up the freeway and engine, VSC trac & Trac Off warning lights all lit up at same time. After calling the dealer and researching forums, I'm pretty sure it's an oxygen sensor or mass air flow (MAF) sensor.
Dealer wants $135 just to diagnose as do other reputable repair shops.
Any way to figure this out without that cash outlay?
I see the responses in this thread and were helpful, but I'm still stuck without knowing for sure what code it is. Don't wanna have to spend more than really necessary, so I'm asking (again).
The soonest anybody can get me in to diagnose is Friday and I'm 2 days into a week of vacation already that I've been planning for 3 months and had some camping/fishing scheduled. To top it all off, today happens to be my birthday (woo hoo!) and I'm stuck without reliable transport.
Do I need to park this machine till diagnosed and repaired or what?

Cel, Fuel/air Or O2 Sensor
You've probably already fixed this by now but I've had the same lights come on twice. First time was a evap canister and the 2nd was a Fuel/Air Ratio sensor, basically a fancy O2 sensor but required for California spec emmissions. It also cost twice as much of course. Install is a snap for the sensor, the canister I had the dealer do it.
I found the part online for less than $60, but you gotta get the right one, may be more:
http://www.rockauto.com/catalog/raframecatalog.php?
carcode=1388707&parttype=5132&a=FRc1388707k501671
Called the dealer again today to see if they would ck the code when I take it in next week for a recall repair (lower ball joint) that Toyota sent me a letter about (dealer pays). They said no and want $135 just to diagnose.
Checked w/AutoZone and Pep Boys to see if they would do for free and they said no, too. They have the scanners for rent (about $165, refunded), so I think I may go that route. Just don't wanna be wrong or could get more expensive. I'm think I'm looking at between $300-400 w/labor.
I got a lot of good information online. Here's a good one, I thought:

and this one has some possible codes and links:

Lemme know if you find a solution.

Read Before You go to the Dealer!
I had this problem show up a couple times recently. The first time, it went away in a few days - before I could get to the dealer, so I just forgot about it. This time it happened again, so I took it in. It turns out that the gas cap was to blame! Not a bad gas cap, mind you, but it just wasn't screwed tight enough. Be sure and try this before you go to the dealer with this problem!
Now, before you all call me an idiot for not tightening the cap enough, know that it's illegal to pump your own gas here in NJ. That's nice when it's 18 degrees out (or 100 degrees!) but you don't have control over how they put the cap back on.
I hope this post saves others the $110 diagnostic fee I just paid.
