My car is showing the code p1406 and p0108 and it started moving very slow and hesitate to move


Welcome to Fixya.

P1406 code means there is a problem with the EGR valve's pintle position. The EGR Valve's pintle could just be stuck in which case the problem could be fixed by cleaning the EGR valve.
If the EGR valve is electronically controlled or cleaning the valve does not fix the problem, you will most likely have to replace the EGR Valve.

P0108 code means there is a problem with the MAP sensor. You should replace it. This sesnsor is usually located between the air filter and the throttle body. It senses how much air is going into the throttle body so the car knows how much fuel to inject.

Thank you for using Fixya!

Wath P1406 Code means on a GMC jimmy 1996,


It's an egr valve problem (exhaust gas return) egr position sensor.
Take off the egr valve and turn it over and see if there is carbon build up in the ports, if there is clean it out with a pipe cleaner and a little carbon cleaner, just spray a little into the ports and clean it out. If that doesn't cure the problem, then either the sensor needs replacing, and or the egr valve.

1996 century


P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1

P0171 code basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. - this could be an open vacuum line.

on your P0301 and your P0171, the first thing I would check is your mass airflow sensor, it's probably fouled, also check the air filter, and vacuum lines for cracks.

P1406 code - EGR Valve Pintle Position Circuit - this basically states that the EGR valve is clogged.

98 Lincoln TC,Cold starts fine ,runs good until warm, then shuts off. No codes,Cranks ok, have spark, PATS ok. No fuel pressure, cant hear fuel pump prime,New Fuel relay. jumped fuel pump - works. I do not hear fuel pump prime up, do not have fuel gauge, but pressing on valve in fuel rail- no pressurized fuel. Fuel regulator seems ok, not leaking / vacuum line dry as a bone. If I let it set for 15 min , it will start up again, but for a few minutes then dies out. If I let it set overnight it starts up perfectly and runs until operating temp is reached then stalls/stumbles, and shuts down. Vacuum is good while cranking, even with no start, Checked Inertia switch in trunk, it is not tripped. I have seen Ford TSB summaries' that mention issues like this , but I am not able to see to description. A point to add, the MAF sensor was cleaned, then I decided to replace it and did not make a difference. I do not have any stored codes, and the PATS is working fine, typical 2 second flash from and once key is inserted a 3 second steady light, then disappears. I have seen the TSB mentioning C103 Connector, it looks fine, I swapped out fuel pump relay with ac relay, still no difference.mention of wires around battery, do not know where to start. in dash service engine light and odometer is normal, seen other posts the say they only have lines, but mine is ok. the start of all of this , I washed engine with regular garden hose, ( not using pressure washer).also in the mean time, rear window defroster stopped working as well, can not say for same reason, but a mention.My problem started after washing engine. this is one of four Panther platform vehicles I owned with exact 4.6l w code engine, which I rinced down before. The only sensor I can think of is Oil pressure , or a corroded wire
