poor fuel economy on 2.0 zetec

hi guys, did a quick search on this but decided to put my own post up to see if anyone can provide any pointers.

 

I'm running a healthy 2.0 zetec with 130 spec inlet, throttle body, ecu etc and a standard XR3i exhaust manifold and system. However the fuel consumption is pretty bad, even when just cruising about. Its in a stripped out mk4 escort so not really a heavy car to pull about. Engine has just had a fresh oil change also.

 

I'm thinking of replacing the lambda sensor, and maybe plugs etc. Car runs perfect and goes like the clappers when you want it too, just i expected a little bit better economy, at the moment i'm getting about 40 miles to a tenner?

You can't use money in a fuel consumption discussion as fuel prices change. Can you clarify your statement by saying how many miles you get to a litre/gallon?

 

Detail exact what injectors, MAF, ECU you're running.

I put £55 of diesel in mine yesterday and will get 510 miles out of it, 2 weeks ago I put in £56 of diesel and got 490 miles.

 

The difference has something to do with only paying £1.109 yesterday and £1.149 a couple of weeks ago,

If you're not running the proper ecu/maf/injectors for the 2L engine then don't expect miracles.

 

Not expecting miracles, just didnt expect it to be so thirsty.

 

Well at least now you know what the effect is of running the wrong stuff.
