make sure there is no material from the old plug left in the hole. clean inside hole with light grade emory cloth. put some hi-temp sealer on the mating surface of the plug. tap into place hollwed side out, edge flush with the engine surface. measure the hole precisely to get the correct size plug. access to hole may be limited.

i would check the plug wires and the coils you check the plug wires for bad spots at night start the motor up and look at the plugs if you see a spark arch out the wire and to a peace of metal then the plug wires need to be replace.

SOURCE: 1999 ford ranger 4x4 4.0L
P1151 means a lean bank 2 O2 sensor
P1152 Means a rich bank 2 O2 sensor
P1309 Means miss fire detected
I would check your fuel injector for fouling
When they foul the will develop a drip
Causing a fuel fluctuation that will have O2 sensors reporting rich and lean voltage changes
This causes the pcm to adjust injector pulses making them shorter and longer.
causing more fuel or less fuel.
From this condition you may see plug fouling.
Also check for leaking or faulty fuel pressure regulator or restricted return line.
Most of the time it wont be a bad O2 sensor the O2 sensor is just doing its job.
You also have already changed the plugs and Map so there already out of the way.
If this helps please give me some feed back
Hope this works for you FixYa

You would need to provide more information for an exact estimate such as auto or manual trans, trans model and engine size. I'll assume it's the most popular 4.0L with an auto trans and 4x4. The book time to remove the transmission (depends on which labor book) is 5.8 hours plus .3 flywheel removal plus approx .5 to replace the plugs. The cooling system will have to be purged of air .8 and the coolant should be replaced. Multiply 7.4 hours times the shop rate example: $99.00 per hour would be approx. $740.00 in labor plus parts. Freeze plugs are cheap and coolant will be approx. $25. Good luck :o)
