Hi , i have a 1997mk3 2.0 16v gti, it has a prob between 3000 and 4000 revs it lacks power and judders i have to drop a gear and get it by 4000 revs so it stop's it can do this in all gears , and when just standing it tick's over not so well either it sounds like it miss but its not as it did this befor i changed the plug's leads ect can anyone help thanks .

Hi there,
My girlfriends car done this too, it was intermittent, but usually between the revs you mention, chucked it onto vag com and it indicated a faulty lamba sensor, when we changed it, it cured the prob.
maby your having the same issue..
good luck

Hi Thomas thanks i will look into this someone else did say it may be the mass air sensor but i'll leave that till last as it will cost a packet lol
thanks Nic

Wont be the maf as 16v's dont have one, they have a map senser which is actually part of the ecu.
I'd start by getting the car checked for any fault codes and as mentioned in other threads those relays can be a cause of these issues aswell and wont do any harm to change em.
-
i have had it checked twice and no codes came up but they did recomend changing the lambda sensor so i will be this week end is see how it is after that then go from there...
-
quick test for lambda, simply unplug it! if problem is solved you need a new one. if you disconnect it it reverts to a base map. other thing it could be is ecu temp sensor, they can fail but still return values within a range the ecu expects, so no fault is flagged. its the 2 pin white one on side of head, always go vag for these :)
-
I had the same problem with mine, got told all sorts of things it could have been (dizzy cap, fuel injectors, ecu/fuel relay) needless to say all got changed but still had the problem.
Have recently found out it was the air flow meter, changed that and the car has been running like a dream.
Try taking off the air flow meter plug and try to drive it !!
-
i just plugged my vag-com 409-1 into my car it came up with position sensor to short or to open to ground, what evar that means but would this cause the problem i have with the car??????
-
for got to say the fault code was G69
-
befor i changed the plug's leads ect can anyone help thanks .
So this problem has occurred since you changed the plug leads, yeah?
Swap 'em out for the old ones first, or a known-good set and then start pulling other things to pieces.
-
G69 is throttle position sesnor, have a look at the wiring to the throttle body, they run along the back of the inlet and get cooked by the exhaust. did you clear the codes first and recheck?
could be an old code that wasnt cleared after problem fixed

Sounds like its refering to the crankshaft position sensor not sure if it would cause a missfire but when i had problems with mine on my old 16v it would keep causing it to cut out and in the end it eventually wouldn't start at all.
Ooops i stand corrected!
-
i have had thisprob since i got the car i have changed , plugs, leads ,dizzy, air filter, petrol filter, ect
-
think i have sorted the prob the wires that run from the position sensor and go round the back of engine , they are all cooked and need replacing so lets hope this sorts it!!!!
thanks for everyones help Nic

have you tried scanning it with the engine running?
Mels polo showed the crank shaft sensor to give this problem of stuttering, but when the engine was running it didnt show the fault code as it didnt have the sensor fitted to it at all. But presumed it did when it was off? If that makes sense.

Yeah, mine would judder at any speed and then sometimes cut out aswell, i would then have to wait a few mins to get it strated as it would just turn over. I have changed all the plugs and leads and air filter and that seems to have cured the juddering and stalling but still sometimes it wont start :/
Going to change ecu relay next :smiley:
-
GET VAGCOM of ebay and run it through a laptop well easy and cheap to use cost me £13 better than £80 at VW, you get the cable and disk thats how ai narrowed it down to my wires on my poss sensor.
-
My car doesnt come up with a fault code lol, so just guessing atm :/
-
mine did not i tryed 3 diff places and they all said the same (no fault) i got the vagcom then it found the prob and my mate had a look and comfirmed it.
-
What was the problem? did it come up with a code then?
Dunno why mine hasnt :/
-
mine would judder between 2500 and 3000 revs anything after that it would run better it would do it in any gear when i plugged the vag com in it came up with possition sensor i check it and the wiring the wiring us f**ked so my mate double checked it at his garage and comfirmed it was causeing the fault so its getting sorted on thursday!
-
right i replaced the wires and throttle body and sensor's and it runs a lot better just need to reset ECU , its stopped juddering between rev's there is only a slight hesitation at 3000 revs for a split sec then its all ok.
-
Change the ECU relay! :rolleyes:
-
it was my fuel relay thanks nic
-
Hey guys,
What number did the relay have on it.167 or 80?I am stomped with the same problem.Irritating jerking all the time.
Thank you for your assistance.

i think it was 80 on it its on the top row 2nd one in from the left. just take it for a run then feel them if 80 or 167 are cold then replace them if warm to touch then they should be ok.
