Kempy 0 Posted July 31, 2008 I'm not really sure where to look to for this problem..I got a valver which I've changed both lift pump and electric pump under the car because they were in need of changing. Before the car went off the road it was very sluggish in 1st and 2nd gears and had very poor throttle performance. Now its not as bad, but still not like my other valver which runs perfectly. Could it be some tuning or timing problems? :shrug: As for fuelling, everything is good up to and including the distributing meter in the bay.. I'm asking really where to go to next? as I'm not sure what it could be Cheers Kempy Quote Share this post Link to post Share on other sites
mattkh 0 Posted July 31, 2008 As for fuelling, everything is good up to and including the distributing meter in the bay.. Hi What spec is the rado. How do you know everything is good upto that point? Quote Share this post Link to post Share on other sites
Kempy 0 Posted July 31, 2008 hia It's a 2.0l 16. Only thing I'm going on is that I've replaced the pumps, filters and have had the pressure tested. But the pressure was tested before I changed the pump under the car, It was don 1 bar. Also the pressure in the metering unit seems fine but I'm no expert. Any Ideas?

PROVR6 0 Posted July 31, 2008 Running rich will show as sooty deposits on the spark plugs. A faulty Lambda can often cause the car to run rich. Worth checking. Quote Share this post Link to post Share on other sites
Kempy 0 Posted July 31, 2008 what is running rich.. exactly I use the term but don't really know what it is :cuckoo: . I will check the plugs and lambda..cheers Quote Share this post Link to post Share on other sites
PROVR6 0 Posted July 31, 2008 Its when there is too much fuel being used. The car needs the correct air/fuel mixture. The lambda or CO2 sensor monitors it and the ECU adjusts the mixture. If the sensor is fubared the ECU can incorrectly increase the fuel ratio. Too little fuel is known as running lean. Running rich is also signified by black smoke out of the exhaust.

Kempy 0 Posted July 31, 2008 The exhaust is not blowing out black smoke. What would then be indicating it was running rich? Would the slow acceleration performance indicate this or would this indicate something else possibly? Quote Share this post Link to post Share on other sites
