Im not a member of a ford fourm but im stumped so, see if anybody can help.
A friend has a escort GTI cab which has an rs2000 I4 lump fitted, now this thing was runnin fine and dandy until he put the std air box back on and it started to idle between 500 and 1500 going up and down.
we have tried a new ICV, air coolant temp sensor, two brand new lamba sensors cleaned the Throttle body, New coil pack from a zetec has replaced the oem ones which sit ontop of the plugs and rewired this was all working fine but the idel was still eratic between 500-1500.
The steering rack needed to be replaced so we cracked on with that, inlet off etc blar blar... The map sensor rubber pipe had a split which I thought would hopefully solve the iratic idel problem. So the rack was done, and we finished putting it all back together and went to start it.
It was cranking but not starting, we have checked all four leads are making spark which they are, and the injection rail is getting fuel. Ive not checked the injectors as yet. we managed to get it started after a number of trys but its has a missfire on low and cuts out. It is a right bollock to actually get started and isnt happy whatso ever.
The only things i can think of are O rings on the injectors are fooked i didnt check these before putting the inlet back on, or the ECU is at fault with the ignition timing.
is there anything else anybody can think of to try and get this fooker up and running again. As i've spent a few hours with my mate replacing things now and its annoying me.
