alfaholic 001 0 Report post Posted October 16, 2011 It was the red seal between the intake and the throttle body, i was about to replace the intake manifold again when i noticed that the seal was flush with the manifold, so i replaced it and the car no longer cuts out BUT its stil got a bit of a low idle, is there any way to adjust it? I just arrived back at home took the car for a highway run, when i left home the fuel gauge was at half. When i returned it was quarter and i done 160km. I drove hard at times (180km/h) and normal (130km/h). is that good consumption? Quote Share this post Link to post Share on other sites
Smaky 73 Report post Posted October 16, 2011 No, that would suggest a faulty Lambda or that the thermstat is stuck open. Quote Share this post Link to post Share on other sites
alfaholic 001 0 Report post Posted October 16, 2011 since the car has been running rich over the last week, could it be possible that the lambda sensor is maybe dirty? could i just clean it? will it be the cause of the hard starting when engine is warm? and yes the thermostat is stuck open because on idle it runs at 90 and when moving it drops down to 60 Quote Share this post Link to post Share on other sites

alfaholic 001 0 Report post Posted October 17, 2011 Smaky I have replaced the Lambda sensor tonight and have driven the car, still no difference yet, will be changing the thermostat soon Just want to know if the spark plugs being worn could cause rough idle??

alfaholic 001 0 Report post Posted October 18, 2011 If I disconnect the coils (1 at a time) there isn't a difference in the idling, if I diconnect any of the injectors it stalls Quote Share this post Link to post Share on other sites

alfaholic 001 0 Report post Posted October 18, 2011 Ok and the disconnecting of the coils as I mentioned above? Quote Share this post Link to post Share on other sites
Smaky 73 Report post Posted October 19, 2011 If it's a CF2 then unplugging the coils doesn't work as each coil runs 2 cylinders and this masks a problem coil, you need to remove them and check the resistance across them lead to lead.
