SOURCE: Drive shaft for 1988 Ford Ranger extended cab

I have a '88 Ranger XLT extra cab 4X4 w/auto tranny (2.9L V6) that had a 2-piece driveshaft on it. After adding a 4" suspension lift, there was a strong vibration whenever I took off from a dead stop. I replaced the drive shaft with a beefed up 1 piece custom built by a shop specializing in drive shafts. The truck no longer had any vibration, and it hooks up immediately on exceleration. I found the shop on Ebay advertising drive shafts. All I had to do was measure the length from the transfer case/Tranny to the rear differential. The length of the new drive shaft allowed me to adjust almost 3/4" so all I had to do was get it close. I also took close up pictures so the shop could match up the correct flange on both ends of the driveshaft. The last thing I had to do was flip the crossmember brace so it wouldn't interfere with the new drive shaft.

P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure
