Hi , when it's hot & humid my 2010 Caravan 3.3 want merge in traffic due to the M.A.P. sensor or manifold absolute pressure sensor stopping the fuel & air flow due to humidity & 100 d. F.
Does anyone know of a modifed M.A.P. sensor to solve this problem or do I have to get a hot rod tune ??? Thanks Bud

 

I check for TSB and Star search, didn't find anything. You may want to check with dealer and ask them if there is a update.
