My Toyota Mr2 Spyder is rattling

Get ECU error codes read at your favorite auto parts store (ask nicely). That should give you a starting point. This is the first thing a dealer would do.

sounds like the coil pack is bad. ignition coil.

Hint: Sometimes when you go to the dealer and look at the part, they can show you on the screen the diagram where it goes!

sounds like cv joint

Replace the entire section before and after the flex. Be sure to look into excessive engine movement, that may have caused this failure. Welds will fail again, quickly.

Sorry to tell you this but you maybe looking at a complete engine rebuild

the noise is the heat sheild area that is rattling around i have the same problem. I was told it was 'pinking' whihc is when the fuel is not quiet right ( as toyota s are designed to run on 95 octane ) but i had metal parts that where loose around the heat sheild and i had them welded back on. Get them mechanics to have a look - it cost me about £60

i would have the gas filter replace.have them put
the code reader on the car and check for poss.code

I got mine from a company called www.electronicmanuals. i think, you can buy it as a download or on a C.D.

it sounds like the clutch actuator is worn out.
The clutch actuator has 2 parts:
1. the clutch master cylinder
2. the clutch slave cylinder.

Try to replace the slave cylinder first, and if it is still not solving the problem, then try to replace the clutch master cylinder

Good Luck
