alfie1 Posted April 20, 2008 Report Share Posted April 20, 2008 Hi there, i wonder if anyone can help me. My lupo will not go over 3000rpm & jumps like a kangaroo, i have already changed lambda sensor on the manifold, camshaft sensor & crankshaft sensor, but on the code reader its now coming up P0321, can anyone tell me what this means & a possible cure for it. Oh by the way, it sometimes cuts out when u pull up. If someone can help i would be truly grateful. THANX. Quote Link to comment Share on other sites More sharing options...
cardaft Posted April 20, 2008 Report Share Posted April 20, 2008 Not sure what the code means, but has it ever had the throttle body cleaned? Might make a difference. Quote Link to comment Share on other sites More sharing options...
LupoEnvy Posted April 21, 2008 Report Share Posted April 21, 2008 Would agree with cardaft and say check the thottle body - perhaps summat is 'sticking' or blocking its movement if you're limited to 3000rpm. Also might explain the cutting out at idle - cable might need re-adjustment? Have you cleaned the air filter box? That can get gunked up, which probably doesn't help at idle. Fuel filter? Just guessing - hope this helps. Quote Link to comment Share on other sites More sharing options...

Also when driving along,say 4 example at a steady 30mph the revs will just drop down and kick back in again whether the engines hot or cold.

Tigz™ Posted April 22, 2008 Report Share Posted April 22, 2008 Have you changed your fuel filter? Quote Link to comment Share on other sites More sharing options...
cardaft Posted April 22, 2008 Report Share Posted April 22, 2008 Next thing id look at are the spark plugs and leads, after ofcourse you have changed the fuel filter if its not been done recently. Quote Link to comment Share on other sites More sharing options...
heartagram Posted April 22, 2008 Report Share Posted April 22, 2008 Try unplugging the throttle body, leaving it for 5 mins and plugging it back in.Was always the best temporary fix when mine kept spitting its dummy. In the end a new inlet manifold and throttle body seemed to remedy it! Quote Link to comment Share on other sites More sharing options...
