While driving my 1994 4.0 fx4 ranger i have a issue., the truck runs as it might be flooded on gas. If i come to a stop after the acceleration or passing the truck drops rpms like it is about to stall. what could it be?
Changed fuel filter three months ago along with plugs and wires. No help

 

Vacuum leak

 

Blhde tis correct

check for any unaccounted air getting into the motor

 

Thanks for your help. I will check it out

 

If it idles funny then it could be a throttle position sensor (TPS) I have a 1994 ranger 4.0 5spd and the idle would drop and almost stall and then would spike to 1000 rpms sensors are junk on these trucks I had to replace my mass airflow sensor(MAF) and my intake air temp sensor(IAT)
