    everything looks dry, could there be a timing issue, or what possible conditions that would lead to this?

What does car do when water in gas tank ?


Depends on how much water, not much if it's only a little (water is heavier than fuel and will sink to the bottom) if the fuel pump starts pumping water, the engine would start to hesitate, sputter or stall.
you can add alcohol to the fuel to remove small amounts of water.

LPG Converted Rodeo Backfires


Backfiring in this case is caused by a lean air/fuel mixture, so I would suggest you richen up the gas supply by either increasing the pressure or the volume of gas being delivered to the engine.

I have to pump the throttle several times and then it starts sometimes and sounds like backfireing allthough its feul injected!


'pumping' a fuel injected engine is NOT like the old days (like with a carb)-if you hold the petal to the floor, it shuts off the injectors-NO petal, the injectors pulse (and dump fuel to an engine that is slow to start). If you are having hard starting, chances are good you have a flooding condition-leaking injectors, leaking O-rings, a damaged fuel pressure regulator could all be re3asons for your hard starting (and backfiring from a flooded engine). You should try to HOLD the petal to the floor and see if that helps-if it does, you should get the fuel regulator checked, replace the injector o-rings, check fuel pressure and might even need to consider replacing injectors themselves (or having them cleaned).

I bought a 89 ford bronco it will back fire through the fuel injection when you give it gas but not all the time


sounds like it is running lean. Check engine light on?

You mean backfiring through the intake manifold right?

A tip in hesitation or backfire is usually a lean condition. If you have a MAF sensor, clean the inside exposed wires with carb cleaner. Do no touch.

When I first start the cars it stalls unless I pat the gas petal a couple of times. Then its okay


this is caused by a slugeged up idle speed control valve and throttle valve, do the following to clean it.
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Rough idle


a cheap and easy thing to try is to clean the carbs. get some carb cleaner and run through your next tank of gas. Also a batch of bad gas can cause the problem too.

Engine hesitation


sounds like unburned fuel in the catylistic converter suddenly burning the fuel as your car picks up speed [causes the rotten egg smell] your hesitation sounds likley to be [tps sensor] throttle position sensor its a variable resistor which is known to breakdown not a difficult repair and can be tested on a multi meter with a bar graph on it yates210456
