Black smoke that smells like tar coming from
I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, diagrams, torque specs, PCV, everything

1993 buick regal limited trouble code 26 and 36 what is a quad driver circuit andwhat are they
A quad driver is what turns the fuel injector on and off. They're part of the PCM and are not replaceable separately. You have to buy a rebuild PCM. BUT, do not do that until you find out WHY the quad drivers went bad. Usually it's caused by a short in the fuel injector coil windings or a short in the harness. If you don't fix it and just replace the PCM, you'll burn out the new PCM
Car pulls right, terrible grinding noise from front right.
TAKE IT BACK WHERE THEY DONE THE LAST LOT OF WORK and tell them to do the complete job again as it sounds like a con job to me as a wheel aligment should last for a year a least and the grinding is in the braking system and something must still be bent ,
Its still under warranty dont pay any more..
Surging problem on an alternator
If the voltage varies a lot or the lights change brightness, then the voltage regulator in the alternator is bad. Left unchecked, instrument lights and any other light bulb can burn out including head lights and brake lights. It can fry automatic ac controls, destroy the radio etc. Get your alternator replaced quickly.
The turn signals in my 1993 Buick Regal work, but
You would have to replace the multifunction switch on the driver side of the steering column. It is not real expensive and if you are handy it is not a real hard job. The multifunction switch does all the directional wiper and headlight controls. The cruise is wired into the handle, but goes down the column. That handle jsut pulls straight out of the multifunction switch.
How to check brake fliud

93 buick regal 3.8 codes 26QMD &42EST PLUS POOR GAS MILAGE
Code 26 is for a problem with one of the quad drivers inside the engine computer, or the wiring harness, and code 42 is for a problem with the ignition module or the control.
You'll need a shop manual with the testing procedures for each code to proceed.
Where is the vacuum modulator located on the 1993 Buick Regal
If it has one
You open the hood & look on top of the
transaxle-- just to the right, of center, of the hood
opening
It will be on top & to the left of the transaxle end cover
& have a tube & small short hose going to it.
Under the hood or on the radiator cross support, should
be a vacuum diagram as well
I have a 1993 buick regal that has a coolant leak.
Good morning, go to the nearest car wash and dry your car engine with air, then park it and put carton below it, then check the lower hose first where it has the clip, if its ok then take off the radiator and let them pressure it, if nothing let me know, have a nice day
