Howdy BB'ers
I'm having trouble with acceleration and the check engine light comes on with the codes for short and long term mixture weak. I have recently tried changing the fuel filter and replacing all the ignition parts....no help. I use chevron prem fuel and occasionally their injection cleaner. should I try and measurre the fuel pressure some where to see if the pump is working? I have an ultrasonic bath where I work does anyone think cleaning the injectors might help? I have 70K miles on her.
Thanks, Timbob
