My 1999 ford escort lx is jolting when accelerating and when idling it feels like it wants to die but doesnt


Water in gas, plugged fuel injector, plugged fuel filter, bad plugs or wires. Its tune-up time! Start with the easy stuff and go from there. Hopefully it's an easy fix.
Could also be plugged catalytic convertercatalytic converter or bad torque converter

Engine running rich


Sounds like a dead coil pack and needs replaced cause you're getting no fire to those plugs and causing a rough idle. Another thing is, that catalytic converter will only turn red because it's plugged up and needs replaced. Have that checked out friend.

Makes a wezzey sound when I gas.. Also no power while driving


Not much information, but from what it sounds your catalytic converter may be restricted or plugged. Temporarily unscrew a O2 sensor and install a pressure gauge 1-10psi. More than 3 psi when you rev the engine means excessive exhaust back pressure and possible converter plugged. I used an old Ford 18mm sparkplug. Broke the porcelain out of it and brazed a 1/8 brake line into the metal sparkplug. Screwed it into the O2 sensor hole (same size and thread pitch). Hooked up an old fuel pump pressure test gauge. Started the engine and momentairly revved the engine using full throttle. Gauge shot up to 10 psi. Catalytic converter was plugged.

Car loses acceleration, starts bucking, then stalls out. there was an odd wind tunnel like sound coming from the back underside of engine? We thought maybe fuel filter so that was changed. no change in...


The sound you describe sometimes happens when you have a plugged catalytic converter. You could remove the converter and drive it to see if the problem goes away or you buy a pressure test kit to check the pressure in the exhaust system upstream from the converter. If the pressure is higher than allowed you have a plugged converter.

Flashing check engine light rough acceleration


flashing check engine light means you are pumping raw fuel into your catalytic converter. DO NOT drive the car like this for long or you will burn out your $500 catalytic converter. Go to Autozone and have them run a scan of your computer and see what it says is wrong. That will get you started. Likely a plug misfire in one or 2 cylinders. Could be bad coils, bad plugs, etc. Sounds lecetrical.

report codes back here.

Check engine light


Had the same codes on my truck. cat converter was plugged. I was told to take the cat off and gut it, then put it back on and it would run fine, but that didn't work. You need a new cat. Might want to replace the o2 sensors before and after the cat also. Hope this helps.
