Hi guys I have 2006 Lotus Elise,
Had to take out the gearbox and change a two gears last week. Car put back together and gears working perfectly. Unfortunately I have noticed since getting the car back that the idle is rough (up and down) Under power it seems to be working fine but in traffic sometimes feels like it wants to stall.
Drove car like this for 3 days and then on Friday got the P0420 Catalyst System Efficiency below threshold code. Cleared code this morning and it has not come back yet but the idle is still iffy.
I have on a stage 2 exhaust that I bought the car with and no decat. Do you think I have a faulty catalytic converter? Faulty o2 sensor? Dirty MAF? Damaged exhaust? What are some fixes for fluctuating idle?
Thanks in advance for any advise!
