Hi guys, new to this forum, my 1.4 12v bravo runs like a pile of poo, idles ok but under load is suffering, it feels like its running out of petrol when accelerating and also on overrun, fuel economy 75-80 mile off half a tank.
I know these engines have a rep for being thirsty but this is terrible, i have changed ect, plugs, ht leads and given it some injector cleaner (forte) no difference, anybody out there had a similar problem or found a cure?? any help or comments appreciated
cheers

The 1.4 is an absolute drunkard as you probably know.

"75-80 mile off half a tank" sound pretty dire even for that but "1/2 a tank" doesn't mean much as Bravos have different size tanks. How many miles per gallon? or miles per £1 is that? It's sounds mighty thirsty

If you're sure the air filter is ok then I'd check/change the lambda sensor. They don't last for ever and can go all sloppy with slow reactions (as you'd expect from a drunk). They're pretty cheap at £25 and if you can change a plug then you can change a lambda sensor. Reset the ECU afterwards and see what happens

Right then, car didnt get plugged in at the weekend, still got the problem obviously:( , some posts on here are describing very similar symptoms as mine, ie throttle depressed in any position car really struggles to accelerate, lift off a bit car runs fine, downhill in gear sometimes feels like its stalling have checked voltages on tps etc all seem fine, its not as bad when cold, but when its warm its really bad, oh deckchair, do you have a contact for lambda sensors? cheapest i could find was about 55 quid!! cheers guys :D

Just read this thread. If the engine coolant gets up to a normal temperature (middle of the gauge), then I'd put the lambda probe as prime suspect. Have a look here for universal lambda probes.

New development on this one guys, it stinks of petrol on startup and is now a pig to get going, also is kangarooing every now and then, regardless of engine temp, any sugestions??

I have reset the ecu and have seen no improvement :bang: , have also ordered a new oxy sensor (thanks for the link hmallett) but i suspect it may not be at fault.

Best to start your own thread for this otherwise people may notice it

Does it judder with the clutch fully up or is it only when engaging the clutch as in pulling away?
Sounds like a clutch fault- oil on the clutch- clutch release bearing or pressure plate problems. If it happens with clutch fully up then possible engine misfiring- plugs, leads etc

Any noises from clutch?

You say clutch feels hard. What's that? Heavier than usual? Not going fully down?
