5000 rpm limit, seems uncurable
« on: 19 August 2013, 15:46 »
I had a misfire and a hall sender code so i replaced the dizzy, Cransk sensor, had timing done sorted the misfire but still only revs to 5000rpm
car was spluttery so the mechanic timed it by ear (no machine)

plugged it into vagcom today and got this  ( should it jump around the way it does? high number to low number?)

(Click on image to play video)


following this i mangaged to get it to block1: 57 Block2: 9/10 cant seem to get it inside the margins, any ideas?

really confused, really need this cured as im only getting 20mpg

If its still hitting 5000RPM. your timing is still out. Also what engine are you referring to?

No i have not seen the video. tbh i dont understand how the blocks work.  :embarrassed:

i've been through this phase myself. Gave car to mechanic for cambelt chnage and he knackered the timing. so had to by a new dizzy and gave it to another mechanc who understood these engines and he fixed it for me.

but all i can tell you is, if its hitting 5000RPM. Its timing issue.

Is the dizzy new? if so its good as one it can rule out the hall sender sensor due to it being a new item and second you will be able to adjust it to tweek timing as it wont be seized.

check the dizzy isn't 180 degree out, it's an easy mistake and will look fine but you have issues with timing etc

yea i'l do this tonight, trouble is the blocks are so close on vag com just unsure as to why they wont marry up.

im gonna take off the engine temp sensor tonight and try timing the ignition.

i was hoping that someone could tell me if whats happening in my video is normal?
