Are you seeing p0171 and 174? If so this could indicate a vacum leak or it can be a weak fuel pump. Start by checking fuel pressure. Its its not around 60psi that or a clogged filter is your issue. Alex
Professional scan test is highly recommended .. All fuel trims and related sensors can be monitored on live data screen .. Invaluable test for these kind of problems!
The test I'm referring to involves MUCH more than simply reading the codes. â–ªï¸https://repairpal.com/repair-shopsâ–ªï¸
