hubballi Posted February 5, 2010 Share Posted February 5, 2010 The only way I can describe my Focus 1.6 is it has started juddering and jerking as if gaps in the fuel getting to engine. It's the same kind of effect as when you try to drive in high gear before it's time to change up. Now lately I have let my fuel run into the flashing light (mainly because it seems to use it in no time at all and I am short of funds so can't afford to fill it up) and think perhaps all the gunk in the tank or dodgy supermarket fuel may have caused this. The last time I put in a tenner at Morrisons and it has got worse since. Even cruising along at around 60 in 5th gear it does it. Someone suggested filling the tank up about half full and blasting down the motorway to clear any blockages. Any ideas ? Quote Link to comment Share on other sites More sharing options...

Any ideas ? dump some injector cleaner stick a tenner in and give it a blast you shouldnt really keep running it in the red however you dont need to fill it up either more fuel=more weight so you use more fuel to haul the car along i rarelky go beyond 15 quid a time as i get better economy that way not as much weight to drag it could be a faulty spark plug lead or coil pack even faulty plugs and causing a misfire easy to see in the dark start her up leave the lights off and take a look under the bonnet you can sometimes see the spark from a faulty lead Quote Link to comment Share on other sites More sharing options...

Any ideas ? sounds like coil pack issues. it could be breaking up causing it to misfire and judder. will also affect fuel economy and its pretty common im afraid.. the old rumours about not letting the fuel get too low are a load of bullsh.. thats why we have inline fuel filters, also the fuel pump draws fuel from the bottom of the tank anyway.

As the cam belt went on the old engine you can imagine the money I have spent on this already and it's only an old 1999 plate. Paid £900 for it but spent over that much on it again. Now the windscreen has cracked which will need doing. I want my old Peugeot 106 back as I had no problems with it. Quote Link to comment Share on other sites More sharing options...

Going to have a look at spark plugs in the week. no offence but ide be wary of youre mechanic if thats his knowledge of cars when you take the plug leads out can you see any water or corrosion if not it may just be that Halfords tool had one before and the leverage is junk try it with a ratchet just be easy on it andwhen refitting put a little bit of copper grease on the thread so it cant rust for the price of new plugs ide replace themn with the leads a simple broken wire on a lead could give you what you feel Quote Link to comment Share on other sites More sharing options...

I have put one of the plugs with a white electrode in the place where the darker plug was. If that is dark after driving it, it will be the coil pack. If it stays the same, it will be just a case of replacing the plugs. Quote Link to comment Share on other sites More sharing options...

artscot79 Posted February 16, 2010 Share Posted February 16, 2010 I can't believe this, it's resorted to how it was again. Gutted :-( well its not leads and not plugs so it reverts to coil pack maf or its a fuelling issue dont waste cash go to the scrappy and take a maf off and a coil pack try each of them if one of them solves the problem you know what oit is if neaither do then its a fuel issue either with the injectors or pump or it could be a sensor is gone totally diagnostics may be in order Quote Link to comment Share on other sites More sharing options...

It now runs better than ever and fingers crossed it will continue. Not a bad job getting the old one off (as a novice with cars) but connecting the HT leads back was a pain. One of them was almost bent and had lost that little clip on the bare copper connection. I got it on in the end but perhaps I should look at getting some new leads too. What I can't understand is if it was the coil pack, why did it seem ok for a while after putting new plugs on ? Surely it would make no difference. Anyway, if it's sorted my fuel consumption which has been high will go down a bit and all for a mere £35 (including air filter and plugs) Quote Link to comment Share on other sites More sharing options...

nabz28 Posted July 8, 2014 Share Posted July 8, 2014 Hi Guys need help. My car started jerking and juddering therefore I done a full service ie changed the spark plugs, air filter, oil filter, oil, brake pads and brake discs. For a short whike the jerking stopped. It started happening again and after reading this forum I decided to change the coil pack and leads. Again it stopoed for a short while and now when driving in gear 3, accelerating betwern 1500 to 2000 rpm it jerks. Sometimes its bad where the car thinks it is going to stall but doesn't or sometimes its a slight judder or a vigorous one. What could it possibly be?!

Laneybel Posted September 1, 2016 Share Posted September 1, 2016 Hey did you guys fix this fault ? I have it with a fiesta 1.5 diesel and it is juddering when I drive between 60 & 70 mph. Not all the time though. It is a 2014 and not many miles on the clock. It has been in and they couldn't find any faults or replicate it. They just checked wheels, suspension and re-aligned everything. Any suggestions would be great Thanks . Quote Link to comment Share on other sites More sharing options...
