Help! Update: Recent Fill-Up/Bad Gas—Maybe??

[Donne Trav]

A recent Thread of mine on the subject of my '94 cutting back upon
acceleration after filling up with Shell gasoline that may be contaminated (water, etc.) and trying to rid the problem by adding Seafoam, Valvoline Gas Treatment, Heet, etc. At that time there was maybe a little over a 1/2 tank of gas. These did not seem solve the problem. As a matter of fact, it got worse. So thinking I may have over done it with the additives, I topped it off with 93 Octane Chevron, hoping to dillute the the additives. This past weekend, I took the car for a drive around the Capital Beltway here in the D.C., Md., Va. area to blow it out & rid the "bad" gas. By the end of the trip it seemed a lot better. Now I'm down to 3 bars/reserve, and its appears to be the worst of all—really riding rough the whole trip. I'm hoping its because of the remaining contaminates in proportion to the remaining fuel before I go on to the more difficult and timely ways of ridding this problem. Keep in mind, I replaced the Fuel Pump, Fuel Filter and Fuel Pressure Regulator this past mid-summer. Please, I need your input & advice to help solve this aggravating problem. ;help

Is there any relationship between the amount of gas in the tank and how bad the problem is? Maybe you are looking at a weak fuel pump or dirty filter.I don't remember if you had changed filter. Could even be the sock in the tank.

Try this

Since you replaced the pump and filter in the last year. I would pull the pump out and as suggested check the pick up filter. When you have the pump out look into the tank and see if you have evidence of water or dirt in the gas. You might try to catch a quart of the gas and let it sit to see if water settles out. Now it goes without saying but I will say it anyway don't be smoking no cigars when you do this.

Thanks for the update I look forward to hearing you found the problem.
