I am not sure what a plug defouler is. The nature of the fouling would indicate the nature of the fault to some extent and provide a clue as to what action is needed. You say the coil and wires are new but you didn't say you had renewed the plug, checked the spark power, distributor cap if it has one or any of the other tasks usually done as part of the fault-finding process. If faults are still active the management will be on the emergency programme and it must be expected the engine wouldn't run as well as normal. Maybe if feels like the CAT is blocked because the CAT is blocked - it is far from unknown.

Don't know where you came up with this one D0131 , No such code . Now if you mean a P0131 it's for a O2 sensor DTC P0131 HO2S Circuit Low Voltage Sensor 1 C0455 Front Steering Position Sensor Circuit EBCM The electronic brake control module (EBCM) receives multiple direct inputs from the steering wheel position sensor. These circuits include, two digital square wave input signals A and B. Phase A or B should toggle high and low every 2 degrees of steering wheel rotation. . The EBCM also receives one analog steering wheel position input on the steering wheel position sensor signal 1 circuit, and is compared to the digital circuits for fault detection. The analog portion of the steering wheel position sensor is supplied a 5-volt reference and low side return circuits from the EBCM. Ignition voltage and ground circuits are supplied directly to the digital portion of the steering wheel position sensor.

Hey Stephanie, I've seen everything from 80-88 ft. pounds. Back on the farm growing up... it was "two grunts". :) Don't forget to use the right tightening procedure. going back and forth across the wheel to alternate nuts as you tighten.

ck the specs for the fuel PSI 60 sounds high.

Check timing .do compression test maybe 180 out

check fuse 16 under rear seat.if fuse is good you have an open circuit between fuse box and rear light.

There are many stages of vibration. The most common is in the steering and USUALLY a steering dampner will correct this. However, your description is not real defined and until the technician actually experiences it, it cannot be properly diagnosed

You have spark ? Try spraying starting fluid in the engine and see if it starts . . videos on youtube for testing cam sensors .

Need some model info on your Blazer to be sure if you have a electric instrument cluster. In the mean time check out this post for some more info. 1990 electric instrument cluster speedo The 1947 Present Chevrolet GMC...

Hoses going to filter adapter are bad about leaking, and factory parts are expensive. If you carefully cut the crimp fittings off, you can use oil remote cooler type hose and clamps to fix it.

According to Chilton's manual on page 159 under "Diesel Engine Emissions Controls" A Crankcase Depression Regulator Valve (CDRV) is used to regulate (meter) the flow of crankcase gases back into the engine to be burned. The CDRV is designed to limit vacuum in the crankcase as the gases are drawn from the valve covers through the CDRV and into the intake manifold. Fresh air enters the engine through the combination filter, check valve, and oil fill cap. The fresh air mixes with blow-by gases and enters both valve covers. The gases pass through a filter installed on the valve covers and are drawn into the connecting tubing. Intake manifold vacuum acts against a spring loaded diaphragm to control the flow of crankcase gases. Higher intake vacuum levels pull the diaphragm closer to the top of the the outlet tube. This reduces the amount of gases being drawn from the crankcase and decreases the vacuum level in the crankcase. As the intake vacuum decreases, the spring pushes the diaphragm away from the top of the outlet tube allowing more gases to flow to the intake manifold. NOTE: Do not allow any solvent to come in contact with the diaphragm of the CDRV because the diaphragm will fail. It sounds like your CDR valve has been compromised. Time for a new one or at least a functioning used one. Credit to - 82Chev @ http://www.dieselplace.com/forum/63-gm-diesel-engines/20-6-2l-diesel-engine/444625-cdr-valve-question.html

No hole behind the carpet. You need to get to where the striker on the glass meets the latch (at the top, center of the tailgate). The latch release actuator has a broken lever that pushes against the latch to release it. Common problem. There is a screw holding the trim panel near the latch area. You are gonna have to force it loose. You need to pull back the panel at the latch area so you can get a tool (or a finger) down inside next to the latch and manually release it. There is a pivot on the latch you need to push down to release the latch. Once opened, remove the trim panel. You will then see a big silver panel covering the inside of the tailgate panel. You will see the actuator that needs replacing (it's held on with rivets). Drill out the rivets and install bolts if you don't have a rivet tool.

beat them off and put on some longer ones.

If you have a spare key try it. It may be the magnetic chip in you key.

It is hardly ever the spark plug or only the spark plug - generally for some reason there is a weak or lost spark and the reason must be found and rectified by carefully checking and then replacing any components found to be edfective - plug wires, coil, distributor cap, rotor (if fitted), wiring, connections and could conceivably even be the ECU. Perhaps the misfire is due to injector trouble... Sometimes a fault with persist even after it has been "cured" until the fault code is erased with diagnostic equipment.
