1992 Chevy Blazer. Complete tune up spark plugs,wires,cap and rotor.
Question: got the car about 2 weeks ago was sitting for about 4 months.

Anyway at the beginning i had no acceleration if i tried to accelerate it would bog out and make
popping sounds out the muffler. So first thing i did was change oil. Oil filter. Air
filter,plugs,wires,cap and rotor. It improved about 20 percent meaning it has some acceleration
but if i try to force it a little more i still here the popping sound out the tail pipe and still bogs out
....Meaning my truck right now is a cow... It has 188k miles on it dont no much about the truck.

You could possibly have a clogged fuel filter that is limiting the amount of gas the engine is
getting, and causing it to bog down. Also, if the vehicle has sat for an extended period of time,
the gasoline that was in it has probably turned bad and separated. You might want to run a few
tanks of premium through it to see if that helps.

Another possibility is a
catalytic converter that is coming apart internally, or blocked up with
deposits. That would cause a bad hesitation and popping when trying to accelerate. You may
want to check timing and make sure it is set correctly. I believe your vehicle should be at 0
degrees at warm idle. Quite a few things to check, I'd start with the easiest like changing the fuel
filter, putting good gas in it, etc.

Checked bulb,
fuses and relay switch seem OK. Only my driver side low beam won’t work.

Ok. Then you need to check that socket for power and ground. Also see it the socket looks
burned. With the lights on and using a
test light, check for power into the socket. I believe it is an
orange or red wires.

If there is no power, then you are going to need to look for a broken wire between the socket and
the relay center. If you do have power, then you need to check the ground side.
The ground is what completes the circuit and the lights will not turn on without it, even if you have good power feed to the circuit.

A bad ground could be a broken wire between the socket and the grounding point, or the point is corroded or loose. Usually a corroded one will cause other electrical problems as well.

A way to test i is to use an Ohmmeter with one lead at the ground wire in the socket and the other to any good clean metal point on the truck. You should not see more that .2 or .3 ohms resistance.
