Right little confused now. Past few weeks the starting issue had gone and there was no let off or air pressure about 5 seconds after the engine was turned off.
Today I took the TB off and cleaned as done so in the guide. Started first time with a tap noise for like half a second if that at all. Every other start was fine, just thinking it was the carb cleaner being sprayed into the inlet that's caused it.
But now after a few starts I'm getting similar problems, it goes to start and struggles to keep idle and dies off but like the issue starting but just a little inbetween running and not starting. Also the 'farting' noise is back. So cant see that its solved the problem or do I have another problem else where?
Could it be glow plugs? What's the life of these things as my car has done 90k now....
I did how ever find the instant reading is more realistic now and the car picks up more just tickling the accelerator
(not all bad news I guess)
