We started having to do two cranks on the car to get it started, but once it starts it's fine.
We checked the codes and it's throwing PO171 and PO174 lean both banks.
Service engine light is on.
THINGS DONE ALREADY:
Undid positive cable (should I have done negative?) On battery before working on MAF
I cleaned the MAF with the correct cleaner. Removed air filter and sprayed it well.
Reconnected battery cable.
SERVICE ENGINE LIGHT IS OUT AND IS STAYING OFF at least for 4 days sofar.
BUT car is still long starting. Either takes a long crank to start, or we mostly do two cranks. BUT it always starts on the second crank.
Car runs totally fine. No noticeable change in fuel economy or performance. Drives the same.
ALSO IMPORTANT TO KNOW:
-Brand new Ford Spark Plugs
-New Gas Filter
-New Oil Change
-Not a new air filter, but coming soon in a week or so.
I'm wondering if the computer is still resetting the starter mix, but it just seems like it has not enough gas to start on the first crank.
What do you think?
We had no problems at all until the long cranking started.
First did the fuel filter
then did the plugs
then the MAF
