I had 99,500 miles on my 01 sienna. When we kept getting the loose gas cap type engine light, it also started to stall on some occasions. When I brought it in they said it was leaking emmissons at the cap, and 3 other places. They would not guarrentee the $1000.00 repair would fix the problem.
 
I did not believe they knew what the problem was, because why would it leak all over the place. It should have been only one location. It was apparent they were trying to get me to repair things that did not need repair.
 
We traded the van in but if it were the oil sludge issue. I would have still been covered under the toyota extended warranty for sludge which is 100k I think. Would have been nice to know this could have been the problem all along.
 
Now that I think about it I am pretty sure a sludge issue would also have caused stalling. But the van would work fine most of the time. Just have that dumb engine light on.

The light was basically just reporting an indirect symptom of the sludge issue.

when were were driving out 2006 Sienna with 35,000 miles on it, home from vacation our "Mait Req" light came on (because it was time for our oil change, nothing to worry about.), then our (-) tire pressure light came on , due to a leek in one tire. As we stopped at the gas station, we put more air in the tire and headed home. the (-) tire pressure light came back on and the three lights jumped on all at once (malfunction indicator lamp) ( VSC) and ( ABS).
When I took the van in to the shop, I told them that I though everything was related and to just do the oil change and we will replace the back tire. If the (malfunction indicator lamp light) does not go off, should I spend the $150 for them to check to see if anythying else is wrong or do you think they are related and wait a while?
I could use some help.
Thanks

Instead of paying $150 why not buy an ODB2 scanner for $99 or so? Then you can use it again next time.
 
Having said that, the fact that 3 lights went on at the same time imply it may be a problem too complex for a DIYer.

"...we stopped at the gas station.."
 
"..three lights jumped on.."
 
CE, VSC, and TC...??
 
I know you said ABS, but...
 
And only "topped off" the fuel, or didn't fully seat the gas cap..??
