SeanSedgwick Posted February 1, 2017 Share Posted February 1, 2017 Hi all, I have a 12 plate Focus Titanium 1.6 TDCI. Everytime I go to set off the car hardly picks up speed, I can be at 4K revs and still be at 5 mph with the engine roaring. But as soon as I change to 2nd gear the turbo kicks in and I'm at 30 before I know it. I have drove a friends car which is the same as mine and it was a lot faster off the mark. Any ideas? It's like my turbo isn't kicking in in 1st gear. Help! Quote Link to comment Share on other sites More sharing options...
jmurray01 Posted February 1, 2017 Share Posted February 1, 2017 1st gear is for taking off only, as soon as you start moving you should be shifting straight into 2nd (between 2,000-2,500RPM). It has nothing to do with power, but the gear ratio, hence why you are reving at 4,000RPM and only going 5MPH. Nothing can change that I'm afraid.

isetta Posted February 1, 2017 Share Posted February 1, 2017 but that answer does not address that he says he drove another of the same model that behaved better (but i don't have any suggestions other then an unlikely one of Ford having changed the mapping at some point and the two cars are either side of the change date ) Quote Link to comment Share on other sites More sharing options...

I understand that, however at 2,500 revs the car is going too slow to change gear. It wants to die when I change into second but when I rev higher in first, second is great. Thats why I feel something is wrong, never felt this in any other car. Quote Link to comment Share on other sites More sharing options...
GaryPL Posted February 1, 2017 Share Posted February 1, 2017 Certainly 5mph in first gear, even for a diesel, is more than possible. I have had several diesel cars and each was capable of doing more than this! Double figures should at least be expected. Quote Link to comment Share on other sites More sharing options...
ajzetecs Posted February 1, 2017 Share Posted February 1, 2017 my 1.8 tdci was doing that, had to put way more revs in 1st of it just died then was ok, my car got worse and power level was bad, turned out was mass air flow, removed plug yo sensor and works fine again 1 Quote Link to comment Share on other sites More sharing options...

isetta Posted February 2, 2017 Share Posted February 2, 2017 take plug off the mass air flow sensor (MAF sensor). this is usually somewhere around the air intake. if faulty it can give false reading and make car run bad. I understand that if you unplug them on some cars (don't remove the sensor, just unplug it) then the ecu uses kind of average reading pre-programmed into it which is better then it being fed totally wrong readings from a faulty sensor. I am not saying i think it is definitely that, I am just explaining what ajzetecs suggested 2 Quote Link to comment Share on other sites More sharing options...
SeanSedgwick Posted February 2, 2017 Author Share Posted February 2, 2017 I will try this tomorrow and let you know the results, thanks. Quote Link to comment Share on other sites More sharing options...

I am not saying i think it is definitely that, I am just explaining what ajzetecs suggested I did this, turned my engine on and my engine light came on and it's reading at -40 degrees... It seems a little more responsive in first, however that could be the way I'm driving it. Quote Link to comment Share on other sites More sharing options...
drsdriver Posted February 2, 2017 Share Posted February 2, 2017 It's not your clutch slipping is it , hence high rpm and no momentum? How many miles the car done ? Quote Link to comment Share on other sites More sharing options...
SeanSedgwick Posted February 2, 2017 Author Share Posted February 2, 2017 I don't think it is, got told I had a strong clutch. 95k miles It seemed better without he maf sensor, but don't want the engine light on, and -40 degrees seems bad lol Quote Link to comment Share on other sites More sharing options...
Albert27 Posted February 2, 2017 Share Posted February 2, 2017 Made a note after reading this post this morning (2008 1.6 tdci) and tried my car out in 1st on my way to work. It's pretty smooth and 10mph was easily achievable.......... Quote Link to comment Share on other sites More sharing options...

That is fixed by the gear ratios. Something must be slipping to get 4k & 5mph, and badly too. A slipping clutch, once it fully engages, may not start slipping again until either the torque goes quite high, or the clutch pedal is pressed. That is "stick-slip" friction. 1 Quote Link to comment Share on other sites More sharing options...
v530anh Posted February 3, 2017 Share Posted February 3, 2017 I would do a clutch fluid flush, or at least do a partial change with a pump. There is a definite problem I just tried first gear last night and I got 24 mph but I did go over 4000 revs. The car did run smoother after that, maybe the high revs burnt some soot out of the car?

SeanSedgwick Posted February 3, 2017 Author Share Posted February 3, 2017 MAF sensor has been cleaned and the car seems normal now, much better at setting off. Thanks everyone 1 Quote Link to comment Share on other sites More sharing options...
