Question about 1994 Toyota MR2

1 Answer

My check engine light needs to be re-set.

I recently started my 1994 MR2 without the air box installed and it immediately set off the check engine light. Now that I have re-installed the air box I would like to re-set the light. I have already tried removing the 15 amp ECM fuse and disconnecting the negative battery terminal but neither method seems to work. Can you help me?

Take the negative cable off again and press and hold the brake pedal down for about 10 seconds. What that does is drains the power from all the capacitors in the engine's computer and will reset the computer properly otherwise leave it off overnight. Let me know how it goes.

Two things... check your oxygen sensor - or just replace it. Have you ever had the check engine light come on while the cruise is on at highway speed? jumper the error check terminals and see if you have any check engine codes showing. Also, see if someone removed the catalytic converter - or get a new one.

I just bought a 86 MR2 it starts right up but then immediately dies. The previous smog test called it a gross polluter.Any ideas?

could be a mass air flow sensor problem, or a manifold pressure sensor problem. may have several major vacumn leaks that are used to sense and control fuel injection supply pressure and fuel flow. Might check manifold pressure. Check vacumn. inspect lines. there are several lines on air flow inlet. there are several vacumn control valves also. Would suggest obtaining an emmisions line chart. There is usually a decal showing the hose routing on the vehicle some where in the engine compartment.

I have a 95 Trans Am myself, with a worked 383 lt1 with full bolt ons. etc Your using the factory tune with that setup? While the check engine light might not be on because of the factory tune i would strongly suggest at the least, getting a mail order tune, and if you can, a dyno tune. You're not seeing the full potential of your setup the way it is now. Are you using an aftermarket mass air flow sensor? The stock mass air flow sensor flows plenty for most setups. Aftermarket sensors can cause driveability issues and many suggest staying away from them.
Are you able to scan the computer to retrieve the codes? It's impossible to diagnose the check engine light without knowing why it's on.

Engine wont start

The mechanic should check on the connection of the wires to the battery and the ignition system . Because of may be there is a wire that have been accidentally been disconnected. When you remove the the speaker box , and the amps out of the car.Check the wires , the fuses and the ignition switch and the ignition switch wires and fuses. It is because when you place the amps and the speaker box ,May be there is a wire that you accidentally disconnected that's why it wont start.When you place back all the equipment to the car.

When installing the air filter are you need to make sure you did not knock off any vacuum lines or electrical connectors. From your description sounds like it wants to run till something tells the computer it is not right. Good luck and have a good day.

A host of problems with my '87 MR2

looks like you have a lot of problems due to poor maintenance. look for a salvage yard around your area. get an AFM, distributor, and coil/ingiter and swap each component one at a time to identify the culprit (I suspect coil). replace all suspect vacuum hoses (again one at a time). Check engine light can be diagnosed to point out your specific problem so there should be no guess work on this. inspect wiring that connects to the coolant sensor. Also check electrical connections (potitve battery post and all chasis ground). air pockets in the cooling system also causes idling problems so make sure you bleed it completely. also inspect air/fuel filter, plugs and plug wires and distributor cap and rotor. replace as neccessary.

good luck
