hi all, iv owned my mondeo for 3 or 4 months now, its coming up to 80,000 on the clock,
At first when i bought it, it was sort of responsive in the acceleration, but after a week i noticed how it accelerated, as i slapped my foot down to pull away the power sort of dissapered but then gradually came back at prob 2000rpm, so after about a month i purchased a induction kit from ebay, the bomz kit. After i fitted it and tried it out i noticed it still has the sloppy pulling power as before but with the nice induction roar. also another wierd power problem came on, as i acclerate past 2500rpm and up the car starts to slow down as if all power had gone then comes back in little steps as if it wants to go but cant, and ill i hear is my induction roaring when it dies and when it tries to go, this happens in all gears when i travel, it does that when im in 4th when i floor it. now a month has gone past after fitting it i then noticed the car starting to judder when i pull away gently and or changing into 2nd or sometimes 3rd, it also judders going in reverse. so i then cleaned the MAF with switch cleaner spray wich evaproates at contact, it then felt abit more confident and pulling away but still the sluggishness was there. i replaced the spark plugs (bosch) to ngk platinum, the piston 1 and 2 spark plug was near enuff had it, but 3 and 4 were resonably ok but deff needed replacing, after that the car still felt the same, no difference was noticable. after a week or 2 the car now seems to have trouble trying to idle correctly but does find the right idle speed (850-900rpm) after it has revd up to 1100rpm down to 300 rpm after 5 or 10 times of doin that. iv also noticed the exhuast tip abit black and spits so i think its running rich as i do often smell fuel either starting or turning off. iv bought a second hand throttle body with throttle sensor attached, planning to replace it this saturday. i wonder if with any hope it will solve this problem. i hope you have a solution to this as im not too sure whats going wrong with it. many thx for the responses to this. steve...
