If you can get the car to Orielly's or Autozone they will check the OBD1 system for free to help you fix the problem.
This sounds like the fuel is not burning in the combustion chamber due to a lack of spark, excess fuel and smoke. On vehicles with a coil pack for every cylinder you would replace the coil pack but on your vehicle you have two coil packs, one for each side. If a coil pack is bad this would cause your problem (left or right). The auto parts people should be able to help you further, but I think this is the problem. (I had a similar problem).
I'd replace the fuel gauge sensor as a first thought, however, before doing that, I'd meter the sensor the times that it blows immediately. You may want to check and see if it blows at a specific fuel level. Trace the wiring to the fuel guage itself and make sure the wire isn't intermittantly shorting somewhere like where it runs through the headlight (if it does) and where it goes into the fuel gauge (or low fuel light). You seem to have tracked the problem to the root area and just need to isolate it to the specific area.
When mine did this it was contaminated fuel. What I am saying is that from storage these will build condensation (water) in the tank. So I emptied mine out in to a clean five gallon bucket and observe, Fuel floats on top of the water and you will see the water bubbles under the fuel. If this is the case you need to dry out the tank as best as you can and then put fuel back in it. Now you can carefully siphon off most of the fuel and reuse it just be careful not to **** up any of the water. If this is not the problem you need to go over the fuel delivery system and clean it out completely
The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.
check if your O2 sensor is working that is the thing telling computer how much fuel to put into motor it is on pipe close to motor your O2 sensor tests how much oxygen is pipe while running and tells to increase or lean back fuel
There are any number possibilities for intermittent running. 1.Bad ground connection at the Ignition Device (transformer, spark box) 2.restricted fuel filter causing fuel starvation 3.crack in the plastic end cover 4.crack in the airline 5.crack in the fuel line 6.crack in the nozzle adapter 7.water in the fuel 8.Others I’m sure I left out You must be the one to troubleshoot & find the cause.
