surges and just stays alive

very rich. too rich. i seem to be losing a bit of fluids on my garage floor but not sure if thats the same problem.

also as u mentioned coolant, my car seem to spray drops of coolant all over my air box and stuff. not much just few drops. coolant level is fine but. could that have anything to do with it?

well being so rich it can be a mixture of either or both the coolant temp sensor and the IAC valve but seeing you have done the iac already its possibly flooding when its cold as its needed for the computer to decide what is needed to keep running at what temp

mine runs a little rich on petrol but i dont mind so much as i run gas more than petrol and id advise finding where the coolant is coming from to be able to spray all over it cant be good

very rich is mormally dead ecu coolant system or vacuam hose for the fuel reg leaking fuel into the inlet

well its had some sort of fluid over it looking at the pic id bet that the seal has been broken at some stage id almost bet its partially burnt out if its the original the seals on the dfi tend to let go get some moisture in there and well you can guess what happens next

it also looks to have a dent near the second coil arrangement thats bad to

did you check the underside of the coils them selves for cracks ?

Yeh all coils are good, no cracks. Your right about the DFI looks like some sort of fluid was on it and the seal on one side is higher then the other side.

have you considered the TPS. a dodgy TPS can make the engine surge and possibly stall. my new(but used) TPS did this to me yesterday. swapped back to the old TPS and better for now but back to my old problems:bang:

I put a brand new one on just lately, so it shouldnt be that.

Should i or could i open it any further to check the inside and re-seal it?

i wouldn't but you can try it might be interesting what damage has occurred just carefully run a Stanly knife around the edges (thats how i inspected mine) then carefully remove the top cover of the dfi then to reseal plaster it in a good silicon after you replace the cap wait to dry (i do the silicone trick even if i dont open it to make sure the seal is good so i dont haveto replace it any time soon) post pics :thumbsup:
