if you have changed anything as in upgraded air intake filter or more it is two things happing.1) Make sure that when your tuning the throttle body remember that vvt-i will keep resetting itself to factory idle.Means piggy back or ecu upgrade is the better of routes due to fact that air and fuel will need to be monitored differently than factory.So try some turbo/egr cleaner spay it good in the throttle body valve. That will clean it out and will run a little bit better. Celica runs best with higher octane since it is high reving motor. This give you some gas mileage back but at the sametime you may want to lighten up on the foot. other than that it will comsume fuel everytime you drive to fast.2) As long you have no engine light problems than the injectors and coils are pretty much going to play a role in fuel comsumption also. The celica does have special injectors and like any can fail or get dirty. Ohming these injector will work. They should all be reading close to the other ones reading. Normally this triggers a light before these checks would need to be looked at!!!Before i would give a ear full of info try the first route. Backing off the gas and higher octane you should see a big differance in the first half tank and or set trip meter and check the distance per tank full. Always make sure you fill it up all the way.Gas pumps don"t no how full you really are, so if they stop short it because the pump sensed that the gas back wash tripped the pump sensor and you may still need another half gallon or more So you may not be completely full. Hope your solution has been long resolved if not contact me.....
you have blown your red line check gaskets from throttlebody gasket directly to the front of the intake. while running motor spray some brake cleaner around the areas one leak and you hear the automatic change in sound of motor. replace and torge to specs.
your wire is touching the car body somewhere and has rubbed a little.Just start following the wire from your fuse to each light. Somewhere you will easily find that where the wire is closest to the body is where you need to inspect.( Mainly a wire) laying directly on frame body is most likely your problem. It can rub just enough to break the outer coating of the wire. Still when it is found close or laying the frame body the hole can be small enough that water between the frame and wire will short the fuse.Best bet any wire touching any part on car is your target.I had a problem like yours and found that a wire was ran over frame even though it was not snug. it was enough the coating rubbed with time. That was just enough when any water got underneath the car it would sit between the wire and frame, Turn on the lights and poof the water and electric was enough to cause ground and short the fuse. On a dry day they normally worked fine unless it vibed against the frame and than metal and electric made ground for a split second and caused it to short the fuse
Hi
The clutch perssure plates seems worne off. you will have to replace them .
You can start by adjusting the clutch setting ...drive for a few days and if still problem persists then go in for a pressure plate change..

Open hood,Disconnect - Neg. battery terminal (ground wire) on Battery side.Disconnect + Pos. side then.Unplug any harness' that are plugged into your transmission.Disconect the Slave and wire it out of the way.Block up the lower left side of the engine and remove the transmission side motor mount.Remove the bolts that hold the transmission onto the engine and slide the transmission off of the splined crank (engine output shaft).The clutch is on the flywheel between the pressure plate and the flywheel.Don't get cheap now... be sure and replace the throw out bearing and pressure plate and have the flywheel resurfaced if marred too.follow the instructions that come with the new clutch kit to install and allign the new clutch kit.Reverse to reinstall.
this obd2 trouble code table can help you understand the meaning of code, for po420, you can try:
Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
inspect the downstream heated oxygen sensor (HO2), replace if necessary.
Replace the catalytic converter.
They meant to say Shift Solenoid, Yes it's bad and yes it is expensive because it will take a transmission shop to replace it and they will want to rebuild the transmission. If this dealer did what I think they did they reset the fault codes while it was on the lot and after you drive the used car off the lot there was no warranty so be ready for a battle.
