What can cause a weak/lean mixture on LH injection cars (I think mine is LH 2.4.2?). The car is a 2.3 carlsson turbo.
my plugs indicate i have weak mixture, and the mpg is quite poor. I also have a problem with performance/boost (as recorded previously)
any help would be appreciated. can i test components that you all (hopefully) suggest could be the cause?how can i do it if it is possible.
I'm thinking air mass?
o2/lambda sensor
air intake temp sensor (is this just applicable to trionic weak mixture?)
Thanks for all your help.again1
