Hi guys, i just found out this great forum, and i hope you can help me out!

I own a 2001 corolla s 1.8 vvt-i 155000km
The problems are...
when the temperature outside is higher than 0 celsius and i start the engine, the engine rev up and down for about a minutes going from 500 to 3500 rpm at each secondes... and there's a sound comming from the engine, like something is sucking air!
the other problem is when i fill the gas tank the engine is not starting...

what i know about the cars is that last week they change the serpentine belt...the water pump, the iridium spark plug and the front cover gasket.

And i have a note on my receipt that says the vsv is bypass po441.

toyota dealer charge me 860$ can. for this and the car still got those problems...if anyone of you have an idea!

Thanks a lot

ps sorry if my english is bad, i usually speak french!

It seems the problem is with EVAP / FUEL system. May be a leak in fuel / evap system or blockage. Fuel/Evap system starts right with gas-cap--->fuel inlet filler pipe--->gas tank--->fuel pump and other components---->fuel lines---->charcol canister---->fuel pressure swtiches & other components like throttle valve, IAC----->Fuel Injector.

If you know about car(s), it's better you inspect and check these components without spending more money or you can ask your friends to spare some of his free time. Coz sometimes cleaning carbon deposites and clogging EVAP/fuel system components will solve the problem.

Your engine is VViT (Variable Valve Ignition Timing), so try to post your email address and somone will mail you PDF for EVAP/Fuel System and Fuel Injection System.

. Hoefully you may be able to solve the problem by yourself.

GOOD LUCK!

I forget to mention...

Always fill gas tank upto 75-85%, leave some margine for air and try to use branded Fuel Injector Cleanner 3 to 4 times, it will clean-up carbon deposites at-least in fuel injection system, and still problem persist the try to diag evap and fuel injection system by components....take your time!

Gasoline in itself has alot of detergents, carbon depostitting shouldnt be an issue.
Mostly injector cleaner is often just kerosene/diesel with a high price.
