im starting to get really depressed with my car now, i havent driven it properly yet and dont know how exciting it should be, its not running on all cylinders, the spark plugs are all sooty, it runs really rich and wont idle. ive replaced the spark plugs, coil pack the leads seem okay, ive cleaned my idle control valve and i dont know what else to do, i dont seem to have any one local enough who knows these engines to help me out either. need some help!!

[rsturbonutter]

Need more info really. Is the car chipped? What injectors is it running?

[fezzRS]

does it misfire on boost cheap leads on tehse am always most of the cars running problems upgrade to decent leads

[fezzRS]

where you located unplug the map sensor aswell see if any change

[georgiocat]

Are you on standard injectors and factory boost?If yes,I would start by measuring the fuel pressure and then the CO content by an exhaust gas analyzer,or via a wideband lamda.Since you say that the plugs are sooty,it must overfuel.If it is way out of specs,it can even struggle to idle...

got great news shes running like a beut now, first inicial drive was ammence, i took it to a garage (boostjunkys) and paid them £50 for a look over, they had it running for me to drive it home after having it towed there, and basically it was the one way valve that goes to the map sensor, it was fluttering back and fourth as its buggered giving incorect readings for fuel and air ratios, and my alternator was dead they claimed that wouldnt be helping anything either, so today i put on a new alternator (bargain only £36) and got a valve from one of my fiesta mates and it is running fine, sooo nice to get rid of the eye burning from over fuelling and no more missfires, love it when its the simple things, i wouldnt of found it myself as im still so new to this engine let alone a turbo charged, i still have a problem to she pulls rediculusly well but i feel scared to drive it like that cause im sure its over boosting ( hit 20psi), now i dont know what internals was done to this car or if its chipped, it does look like the person before me thought strapping big things to it and turning everything up will make the car quick as f### but i know for sure its not that simple as it will also kill it as quickly as it accelerates, so after looking at the bottom of the ecu it has an origional blanker in place and wondering if either my amal valve isnt working or if the actuator is wound right in, guessing i shall have to check both, cheers for the replys by the way guys

[gazaboi]

its on standard injectors to btw so safe to assume its not chipped for that very reason

[stevo™]

get rid of the amal valve there prone to leaking and most bin them once they up the power

You can really run what ever boost u want without a chip but its when the ecu starts to read the higher inlet temps that come with high boost thats when the ecu stuts the boost off. to save the engine, then disconnect the battery and start again lol

Glad you fixed the problem.Just a small correction.The round thingy that is attached on the vacuum line to the map sensor is not a one way valve,it is a fuel trap.It is there to keep the fuel vapours away from the map sensor.If you install a one way valve on the line,then the map won't give correct readings...although many people think it is a oneway valve,in reality it is not.Also you run on stoch injectors on 1st stage too.165 hp chip is on stndard injectors,it just removes boost limiter and increases boost and gives the appropriate fuelling.If you don't hit boost limit then I guess you are ok...although the best way to know if your engine runs ok and not lean under boost,is to measure the AFR under boost.Especially if there are not well known tuners in your area with good reputation on rst's,(like here in Greece where I live),a good invest is buy a wideband and install it so you can always have a picture of your engine running This is what I did.Also an alternator that is not working as it should,could create a lot of problems.

How can the EFI management run on whatever boost we want...?It has boost limiter,anything above the boost limit will throw ECU to safe mode.The problem is not only the temperature readings from the intake air...and I don't think it is to realistic to disconnect the battery every time you hit boost limit...

[ben26]

U can turn the boost up with the actuator to what ever u want and u can drive it for a few miles. But like i said as soon as the inlet temps rise it shuts the ecu down. Then u have to disconnect the battery.

But i would not reccomend this btw. !

so do i still need to replace the valve or fuel catch, i think its correct name is a vacuum seperator as ive found 2 on ebay under that name and have one coming my way, also my car goes like f### with the boost it goes up too, im still not using it everyday at the moment until i feel confident its okay too, spose it dont help i wanna use it in september to go on holiday to the south coast so i want it reliable, she idles a tiny bit lumpy but here thats about normal plus would these cars smoke a bit if there not used all the time

[gazaboi]

and something else has apeared to me now, its a bit jerky when you poodle around slowly, i at first thought it was just my clutch control but it does seem to be a bit more than that, i have got the accelerator tought so its responsive dunno if that would cause it or if it would still be a running issue

[georgiocat]

If you want to replace it,ok,it will do no harm.Keep in mind that it will let air,(or vacuum),pass from both sides,it is not a one way valve.You must not use a one way valve on the vacuum line to the map sensor.If it is running lumpy,check for vacuum leaks.Perhaps a hose is split or nto tightened.Also check the brake booster tube,the hard tube from the inlet manifold that goes to the brake booster,they sometimes leak.Regarding feeling a bit jerky if you drive it around slowly,mine does that too if you drive it like that for some time...it doesn't like it to...relax for long times as it seems If it is too intense,I would think for the tps,but I don't think it will make a lot of differnence if you replace it,unless it is completely knackered.

You can really run what ever boost u want without a chip

From memory, std management has boost cut programmed in at 10psi. Chipping the ECU moves (not removes) the boost limit.
