Escort mk4 - Weird running problem
Hi Brits.
I own a ford escort mk4 cl, modded to a 1990 spec Xr3i Efi engine.
It have some strange issues tho, i have no clue how to fix it.
Lets start at the beginning:
When the car have been turned off for a couple of hours (typical 5+) it starts "okay" runs okay for a couple of yards and then it starts to "jump"/driving rough. It starts jumping around like im zapping the gaspedal on/off, but ONLY when I drive it nice, if i just floor it (even at 1500rpm) it stops jumping. untill i stop flooring it, then it starts again. After I pass 1km it stops acting weird but.. Now its still jumpy when i drive economical or hold a certain speed (like 60mph) ,, Only way i can get around in the city when im going back from work is to drive between idle and full throttle + raping my already worn clutch if i wanna avoid the damn jumping!!
When i floor it, its like its laggy? It waits for ˝-1 second before taking the throttle and then gives a huge jump feeling like the engine is gonna fall though the bottom, this is only when i kick it! if i take 2 second and increase the throttle smoothly theres no jump
Bonus info:
No problems in idle. (sometimes it goes swinging 100 +/-)
Engine = Cvh 1.6 8v efi. WITH lamdba/hego sensor
Obs: Also when its cold, it runs for like 1-2 seconds on the starter, sometimes when it hot i starts on the button? :S
So what is it? Something with the ecu? vacuum? Worn fuel pump?
Im sorry for my bad English.
Hope you can understand my text.

Danzul - Wow i hope this aint my prob, but i know one of my valve guides is broken and the stemseal cant sit 100% on it, so now sometimes it puff bluesmoke when i start, but still only use 1 liter pr 8000 km O_o
Thanks for your input

put it this way if ya engine starts to feel like its getting quicker stop driving it and check it, i know its not something ya wanna here but my engine is fuck uses a litre of water and quarter litre of oil head gaskets gone valve sills are none existent but it gets ragged every day? so a little bit of oil should be fine, start by checking fuel filter, even check the inlet aint leaking
