Basically car has been running ok... but recently the engine management/injector warning light has been flashing up on the dash.
At first it was coming on for a moment at a time then vanishing, and some trips wouldn't come on at all.
car was running perfectly, with maybe a hint of reluctance to go when off boost.
Over the last couple of days the prob has got worse, the light is on for entire journeys and the hesitance is still noticable. Driving home thisevening i was having trouble holding a steady 80mph without being on boost which isn't normal.
I have changed the map sensor which made no difference, and have also got a new lambda sensor to try. I would guess i should also change the standard injector.
The other day when i took Ghostwkd in my car he commented that it sounded like it was pinking. if this is the case i don't know whether i may have damaged summit like the spark plugs or something? the pistons are knackered already but the idle seems to be fine and the car doesn't randomly conk out and still runs at a little below normal operating temp with the low temp thermo :) cars running rich not lean so i doubt that underfuelling is occuring...
jus wondering if there are any other things i should check?

any help gratefully recieved :worship:

Not sure if its mf2 related tho, coz it comes on whether boosting or not, and mf2 is workin fine.
Have tried a new lambda and a new injector and although its running smooth now the light is still on.
I guess because of the melted pistons the car has realised that is on the way out and its tryin to warn me about one of the ports or summit (n) :(

still new lo comp 1242 on the way hopefully :) jus gotta keep this one ticking over until its ready to be dropped in :)
 
give me a shout if you want me to pick it up when its done as you know its on my way to work everyday, can drop it down aswell if ya need, posh alex. (y)
