Still lagging - Advice please **PICTURES ADDED**

OK, My car is still lagging in power.

It is a completely standard Ford Orion 1.6 (NOT Injection) J reg so 91/92.

I don't know why, but it is not pulling away as it should be. When i put my foot down to pull away, the car will more often than not judder and sound like it is going to stall, if i release the accel and pump it, it comes back into life. This is most annoying at junctions and round a bouts.

Also when accelerating through the gears it goes quite sluggish up until about 4k RPM where it all of a sudden kicks into life.

I have so far

1) Put some Redex through it
2) Changed Plugs
3) Changed Leads
4) Cleaned out Air Filter

I noticed the car was starting to make a loud noise as well, like the exhaust was gone, but i could onl see a tiny hole on the middle box, so i looked under the bonnet. Now i don't know the proper names for things, but i tightened up the two bolts that sit just below the unit the HT leads plug into as it looked loose and to be the cause of the noise. I will charge my camera and go outside and take a picture of what i mean. Anyway that quitened the noise down a bit.

What else could be wrong with my car? Also it is eating unleaded like a Jag on a stag weekend. £37 to fill her up gets me 200 miles if i'm lucky.

Change the fuel filter, they're only like £5-10. :)

The exhaust could have something to do with the poor fuel economy. How is the engine temperature?

Get a new distributer cap too, well worth it for £5.
 
OK, see pictures below. That's the boplt i tightened to stop the noise, whats that holding on? Are there more under that cover? Could this be effecting performance?

Distributor cap? Is that the thig that sits under the cap the HT leads go onto?

Where does the fuel filter go, and is it easy to fit? I am in o ay a mechanic so don't know lamer terms, etc. I'mm willing to try anything though :)

Yep, the distributer cap is that box thing where all the spark plug leads go into. :)

The fuel filter is in the engine bay there somewhere, I'll have a look for it in a min but i'm sure there will be somebody here who will know where she is.

It's easy to fit. It's basically just a canister with a pipe on either end. You just clamp the fuel pipes and then quickly attach them back on, though you may have to do it a different way, like depressurise the system i'm not sure but it's easy to do. :)
 
I can't see it mate. I'd imagine it's at the back of the engine bay there somewhere behind that big black air filter housing.

Just find the pipes that go into the carb and follow them, they should take you to the fuel filter (canister). Hope that helps. :)

Exhaust manifold heat shield.

Check around the hoses for hissing noises indicating a leak.

Check plug gaps, plug and leads condition.
 
This sounds either like an ignition problem, or overfuelling. It's not a fuel supply issue (so your filter isn't blocked) as you're still getting enough to run the engine in the higher regions of the rev range.

Your car have an automatic or a manual choke?
 
There's ya problem then. Time to dig into the Haynes to find out how to test or remove it. I suspect if you remove your air filter you'll be able to get a much better look at the carb and autochoke unit. Might have just become disconnected! :)
 
Well if you take the aircleaner assembly off (large black frying pan on top of your engine) ....you'll be able to see your carb (which on the side somewhere will have the autochoke unit).

If you then refer to Haynes, you'll be able to find out how to test if it's working properly, or at least how to disconnect it and turn it off to see if that's the source of the problems :)
 
If it's anything like my old Fiesta it was the air flow sensor that was causing problems with lack of power/flat spots/inconsistent accelleration. Not sure where it would be for your car but a quick browse in a haynes manual should locate it for you.
