Misfire problem 8 Years, 10 Months ago Karma: 0
Hi, I'm looking for some help. I have a 1995 mr2 turbo and my problem is that it will drive perfect for 2-3 minutes and then the engine light comes on and a missfire comes into the engine, the fault code is 52 ( knock sensor), I put a knock sensor into it but I still have the same problem, has anybody experienced this before? Any help greatly appreciated

What fuel are you using 95 or higher octane rating.

Have you checked all your spark plugs?
It seems obvious but sometimes overlooked.

I use the normal unleaded petrol, I changed the plugs and leads when I changed these the car would drive a bit further before the missfire comes in

Put 97/8 octane in it and some millers octane booster, then see if the problem reappears.

After that it is time to check stuff that cost money rather than throwing parts at the problem.
