Dont know where to start really?! I`ve replaced and cleaned just about everything possible on my xe now and still no better performance. One thing i will say is it seems too good on fuel since my lack of power. Also,it coughs and splutters and holds back more when cold. Can anyone help? Going to change the fuel sender unit tomorrow as no guage,so will check all other pipes on the tank for blockages.
have you checked the fuel pressure? or the fuel filter, suprising how many times i'v heard of or fixed engines that aint performing quite right with just a £12 fuel filter, apologies if you've tried these things already
Possible ht leads(thought they`d have checked spark on a tune!),so i replaced them. non gm lambda sensor and possible break in wiring loom which i still haven`t checked for continuities, but thought it would have shown up on management light.
Coughing and spluttering when cold,and holding back for first 10 secs, poor idling, slow pick up on revs, and still holding back throughout the revs even when warmed up. cant really think of much that i haven`t checked. lifters are quite noisy though?
er, best way is to try another one really, it may be breaking down giving a weak spark so voltages would be the same at the connector,got any mate witht the same motor? if not Andyk will know how to check the coil pack i would think
