    what he did was disable the intake air temp sensor. this makes the car think it is cold outside all the time. it sees cold air and adds more fuel to compensate. more fuel means more power. but it also means reduced mileage and prevents cars computer from doing what it was designed to do. Replace the iat sensor hook back up the other sensors and we will go from there. doing this only adds a couple horsepower and with price of gas you would probably rather have the mileage.

Its a 93 toyota celica it stopped runnin while driving. i towed it home when i tried to start it, it cranked like twice as fast as usual and wont fire.

your timing belt may have snapped!! When this happens, there is no compression preventing the engine to start up. Because there is no compression, the engine spines easily. Remove upper timing belt cover and inspect the belt. If broken, replace the water pump belt and tensioner pulley $400-$650 job!!

Dash broad lights not working and u turn dimmer

If its none of the fuses, it will most likely be the dimmer switch.

This happened to my eclipse also, although I wasnt so lucky, I needed a new computer, while the dimmer switch and fuses were fine.

Replaced head on a 93 starwagon

ok is this an eclipse? and is it a 2.0? and if so then this is very common and i do not recommend doing it urself but if u must be a do it yourself type person then be careful there alot of ways to mess this up and if u do it worng u could have pre-detonation knock or even bend and break valves or break piston headsand if ur head was resurfaced then it could have been shaved down to far and it will never line up properly but i would put all pistons hlaf stroke high and line up the camshafts then very carfully align the crank thats the easiest way to set the timing on an eclipse
