reset your ECU, remove your positive terminal for at least 5 mins then hook back up see if it works.

didnt work any other ideas why?

What kind of fuel are you using?
Also, did you check your battery and alternator?

[gasman]

91 octane

Do the idiot lights go on? (Check engine, radiator, brake etc)
Are there any other symptoms?

Also, check to see if you have any vacuum leaks.

all lights go on and all just doesnt boost when you step on it.
and how do you cheeck for vacuum leaks?

You definately have an alternator/battery power related problem. First of all, how many volts is your battery meter showing? If you're getting around 12 - 14v, you're fine, but even though, check to see if your battery needs replacing.

Secondly, get your alternator checked out. It may be a problem where it doesn't hold the charge for your battery. Toyota designed the MR2 to flash all its lights when there's something battery/alternator related.

Go get that checked out first. I don't think its vacuum related at the moment from what you tell me.
