Mixture is controlled by the length of time the injector is open,also known as duty cycle,fuel pressure is also critical.


Have scanner if you need it .

If I remember correctly there is a fuel micro switch in the tps to cut the pump off on overun to stop excess fuelling.

I should have an LED turn up in the post tomorrow so I can interogate the ecu to see is there are any (or more likely how many)error codes. I am going to replace the temperature sender that goes to the ecu. I will check the MAF next as well.

Do you fancy having a look at it? I can supply you with unlimited cups of tea lol

Sure, you only have to ask.

When ?

[Davidbolam]

Thanks . I will run the diagnostic test first then drop you a message

My old mx5 had similar problem was using a tank of fuel to do 10 miles and overheating cause I had to keep the rev's on to make it move

Turned out it was plug leads changed plugs and put a decent set of leads on and it was cured

I'm on my 3rd set of leads. I'm going to see what the diagnostic light says tomorrow. The plugs are black so they may need changing but they have only turned black. I did replace the plugs when I put the ending in.

I've just tried to reset the base idle.
