I have a 1987 Ford Ranger and sometimes when you start it up (hot or cold) the engine runs so ruff that it feels like only three of the six plugs are firing. The engine shakes so hard that it feels like it's going to jump right out of the truck. Then after a while it starts to run OK. Sometimes when you come to a stop sign, the engine dies. It usually starts right away and runs OK, but sometimes it doesn't. It has a manual trans, V6, 2.9L engine with twin gas tanks. The engine is fuel injected with electrical ignition. I keep the engine tuned and with regular oil changes. I just replaced the air filter, spark plug wires and distributor cap about 8 months ago. Twice I've added 'Heet' products to the gas tanks to get rid of any possible water in the gas. Also, added a product to try and clean out the fuel injectors. The other day it started and would not take the gas at all and the engine died each time. The battery finally died and had to put it on a battery charger. The next day it started like nothing was wrong. The truck never acts up when you are driving down the road at a constant speed or slowing down. Can you please help? Thanks! Rocky R.
