Question about 1986 Toyota MR2
It's a common problem called 'hunting'. It rev's on it's own yes ?
You will have air in the coolant system, it's quite a long process to bleed properly and you must get it right. My advise is have a look on my club www.imoc.co.uk, we have a mk1 section and some fantastic how to's. All your problem's will be covered. check your expansion tank cap for sign's of cracking as well. Mine has just gone on me and has caused the hunting as it allow's air to be sucked into the coolant causing bubble's to pass the temp sensor and give the ECU a false reading wich adjust's the fuel injected.
We are a very freindly bunch with a lot of experience and will be able to help you.
