My 01 ford ranger 2.3 5 speed has been getting engine code p0171 for about 4000 miles now. Bank 1 system to lean. I replaced the intake manifold about 15000 miles ago. I took the intake manifold off to reinsure everything was sealed well. I replaced my pcv valve and my fuel filter recently. I propane tested all of my vacuum lines to check for leaks. Everything is sealed well. I took it to the ford dealership after taking the manifold off to have them check the code. They found a vacuum leak that was just a hose disconnected. They re attached it and my light still came back. I figure the vacuum line they found disconnected was probably one I forgot to hook up when I put the manifold back on. My mechanic found engine code p1537 IMRC stuck open. Ford tested the IMRC and said it is functioning properly. I frequently get it scanned and cleared and keep getting p0171 bank 1 system to lean. I have tried everything I could think of and already spent 600$ to mechanic/ford to get rid of it with no luck. Anyone had a similiar problem or have suggestions??? Or know of a good place near the SF Bay Area?
