Mitsubishi Colt 5-door - Ecu problems - Rosie4215

I have a 54 plate colt epuippe. Whilst driving the engine light came on and after a few seconds the coolent light came on as well. At the same time as the coolent light the engine shudders and the revs go up and down. Its very easy to stall at this point. After this the collent light goes off and now and again the engine light too. This happens from a few minutes into the drive and every few mins after that.

I have taken it to a few garages and they havent been able to identify the problem. Its been plugged in to diagnose and it is still unclear what the actual problem is except its an ECU problem. They also say that they wont touch it as its electronic/ecu problem.

I would be grateful for any info anyone has on this and if its worth spending the money on. I have been told only the dalership can help and i know thats very expensive.

Many thanks.

What about taking it to an auto electrician? It maybe only the coolant temperature sensor faulty. Alternatively taking it to Mitsubishi may not be as bad as you think, they should be able to diagnose the exact fault without randomly fitting parts.

Your 2 alternatives are scrap it or fix it.

Why not speak to a Mitsubishi dealer (or more than one if you are lucky locally), it may not be such a shock.

Try disconnecting the coolant temperature sensor and substituting it with a component with a fixed resistance value such as a bulb and see if the problem disappears.
