jacks906 Posted May 20, 2009 Share Posted May 20, 2009 what sort of RPM are you looking at at the speeds stated? dave Quote Link to comment Share on other sites More sharing options...
C18RCH Posted May 20, 2009 Share Posted May 20, 2009 My Td5 will do 45 MPH and 60 MPH in 3rd and 4th respectively any more than this and you would be over revving the engine. I would suspect that it is the rev limmiter that is stopping you. Although you should not be revving the engine that hard anyway. Quote Link to comment Share on other sites More sharing options...
Gilslandy Posted May 20, 2009 Author Share Posted May 20, 2009 hi guys, thanks alot for the replies, jacks906, the thing is that i dont have a rev counter, as instead i have the clock. i have to find an original rev counter that fits instead of the clock. c18rch, the speed i mentioned are km/hr, sorry here in malta we use km/hr. i think i solved the problem, i looked at the alternator to see whats going wrong with it as the light was blinking when reving and noticed a loose main. i fixed it and went for a ride...it seems that the loss of power at the said speeds is ok now. cannot understand whats the connection between the alternator and the loss of power at certain speeds. thanks alot gil Quote Link to comment Share on other sites More sharing options...
M&S Posted May 20, 2009 Share Posted May 20, 2009 If it happens again unplug the Mass Air Flow sensor (the black plug on the sensor that is connected just near the air filter box). Then try driving again. The ECU will put in a default reading for the MAF sensor. If it drives ok then it's time for a new sensor is about £90 I think, but will cure the problem. Sounds like exactly the problem I had with my TD5. Quote Link to comment Share on other sites More sharing options...
