Seanomurray 0 Posted September 28, 2013 Share Posted September 28, 2013 Hi all,I have a 2000 1.4 corolla saloon.I recently changed the engine as the old one was gone.Had it running really well until suddenly it went really lumpy on idle.Sometimes when it warms up it's ok but ticks over at 1500rpm!! Great pull through the gears despite this problem!Tried putting the throttle body off the old engine on it to try it and made no improvement!Really Irritated by it now!!Any suggestions?Regards,Sean Quote Link to post Share on other sites
oldcodger 342 Posted September 28, 2013 Share Posted September 28, 2013 Hi,A possible cause, assuming the Battery has been disconnect it can take about 30 mins of driving before the ECU re-learns the right values for tickover, until then its all over the place.

Seanomurray 0 Posted September 29, 2013 Author Share Posted September 29, 2013 Hi, Thanks for you're reply.I solved the problem by plugging in a cheap diagnostics reader i got off ebay for a tenner.Turned out to be the cam position sensor.When sensor was replaced the car is perfect.
