1992 GMC Sonoma Questions & Answers
1992 gmc sonoma pick up egr system diagnostic procedures. help?!
Exhaust Gas Recirculation systems do not cause you symtoms, when the EGR fails it leaks exhaust gases into the cylinders, this causes a very very rough idle and a stall, the valve gets hot when it leaks at idle. Run a self test on the ECM and try to get any trouble codes stored in it, Kragen auto I hear does this for free.
92 GMC sonoma 2.5L 4cylinder - replaced
How about no spark or did you screw up the firing order when you replaced the plug wires? It is easy to do.Typically there are 2 things to get an engine to fire that's fuel and spark. other things will make it run bad but not even a short rumble when you use starting fluid, there is no ignition. Get a spark test tool from the auto parts store. Check the firing order and be sure your wires are in the correct order.
Need to know how to set linkage on 1992 GMC Sonoma
With the car not running, get someone to push the pedal all the way down and check to see if the throttle valve is fully open.
If it is, chances are the engine is being starved of fuel (plugged fuel filter, plugged or undersized supply line, faulty pump, faulty regulator, etc.) - check the fuel pressure at the engine.
If it isn't, there is probably no cable adjustment and you will have to replace the linkage cable.
I used a easy out and broke it too...!!!
You have just learned the lesson that easy outs aren't and generally devices for removing broken studs and bolts have a very limited use. If a bolt has sheared because it is corroded it is unlikely to be moved by the modest force an easy out can apply especially when the more force that is applied to the easy out, the more the broken bolt is expanded in the hole and the tighter it becomes...
Easy outs are great for coarse threaded bolts that have snapped due to overtightening...
Drilling and tapping mostly provides the answer but this also produces problems in a blind hole. Drilling and tapping oversize is best and using helicoils or making a much larger threaded hole and plugging it with a large bolt and then drilling and tapping to the original size produces good results. Double diameter studs can be custom made to overcome many problems.
Before resorting to drilling I usually try and get the broken stud out and laying a washer over the broken part and then using the mig welder at full output weld the washer to the end of the stud and then weld a nut onto that can produce good results.
Any easy fix for DIY...?
no easy fix for diy people or for qualified mechanics either
there are a variety of "eazy out" tools that can be used depending on accessibility to the broken fitting
probably the best is a fluted type that is hammered into the fitting and then used in conjunction with a spanner may get it out
the left hand tapered type generally expand the brass into the hole making it more difficult to turn but it is an option
if there is space you can buy a left hand drill bit ( available from specialist tool shops )( as opposed to a standard drill bit that cuts in the clockwise direction) that you use with the drill in a reverse direction and this tends to unwind the broken part out as it is drilling
