Okay so i own an EF ford fairmont, and im having problems with my acceleration.
when i plant the foot on take off, the car seems like it loses all power and then after a bit it just screams and takes off like a rocket. car is practically standard other then exhaust. how can i fix this? |

Check you accelerator cable for frayed strands and make sure it moves freely. It might be sticking or stretched. After that, maybe look at the condition of the TPS (on the side of the throttle body).
How long has it been since the engine had a tune-up?

Shortshift is right, a good way to check the accelerator cable is to take the intake tubing off the throttle body, stand in the door of the car and watch the throttle body butterfly opening/closing as you plant the accelerator pedal (with the car off
 ). Make sure it moves smoothly and that it's all the way open when the accelerator pedal is planted to the floor. If not, replace the cable.If the cable is all good it could be a fuel issue, check/replace fuel filter first then move onto other things if necessary. |

okay will definatly check the throttle cable then, its very likely that it could be damaged.
the leads a brand new so it definatly isnt that as i did have issues with them and replaced them and sorted that all out. i also plan to change the fuel filter on it anyway so will do that tommorow and see what i come up with. cheers guys will let you know how it goes. |

"will let you know how it goes"
Good luck with it - and please do post what ends up happening with it - there are lots of threads that end up hanging with no posted result - which is frustrating when you're doing a later search for exactly that problem.

Sorry, my earlier post was a bit heavy on - I've edited it down - I wasn't having a go at you and don't feel it necessary to give minute by minute updates - just posting what eventually fixes it would be nice is all

Does it feel like it misses??? I had the same thing in my EF and it ended up being a dead coil pack. It would miss under load (taking off from lights and r-a-b) but once over about 2500rpm it was good again.
I suggest that as it is something fairly simple and fairly cheap to replace.

the coil pack has been replaced with a brand new bosch one, it also has brand new leads and spark plugs. so spark shouldnt be the issue as its already been checked out fully.
once the fuel filter is replaced ill have to give it another run and see how it goesi think it will make a huge improvement cause the old one was really dirty |

how many km's has your car done. i had the same problem. put new leads and spark plugs in. new coil pack, new fuel filter. ended up running worse. a mate and i were having a few beers and we both come up with it could be the fuel pump. put a new fuel pump in and went like brand new. a year ago and havent had a problem yet.

have replaced the fuel filter and it has made a significant difference, but it still bogs down a bit when i take off hard. not too sure what else there is i can do? any suggestions?

couple of things:
has it got a blocked cat or exhaust? do a compression check, is it down on compression? blocked injectors maybe? stuffed oxygen sensor? blocked air filter? fuel pressure regulator? could the ignition TIMING be out? wonder if it might have a blown headgasket? there's a few ideas to work with Cheers, Gab |

umm exhaust should be fine but i have a hi flow cat on the way anyway, and ill be putting extractors on at the same time.
umm compression im not to sure on should be fine but as i just did the headgasket, which wasnt actually gone, but was on its way out. air filter is brand new but only a cheap one, im gonna put a pod on it soon so well see what that changes. oxygen sensor im not sure but will put one i know is working in when i put the extractors in. blocked injectors could be likely as they did run a bit of crappy fuel through them for a while and they also sat around for a while. but it runs exactly the same on gas. umm ignition timing, how can i check that? and also the fuel pressure regulator? |
