Engine sputtering

Okay so this was an issues that I dreaded, but knew was most likely going to occur.

I was having engine issues before this. My car was sputtering a little when I accelerated. I attributed it to a bad fuel pump. Thursday after work I barely made it home. The car sputtered all the way home. I had no power. I was going 0-30mph in a mile topping out at 30-35mph. So this weekend I replaced the fuel pump, fuel filter, Oxygen sensor, and I dropped the fuel tank and cleaned it. There was a significant amount of rust in my tank. Not to mention all the sludge I wiped out of the tank. All of that and I'm still sputtering... no power... no acceleration. My guess at this point is I may still have something stuck in the system.

I pulled the battery cables to reset the o2 sensor code, but it popped back on. My exhaust smells foul like a high carbon type scent. The engine also backfires. Now if I shut the car off for a while all of the issues will go away periodically.

Here's where I am

Re: Engine sputtering

Try a different/new distributor + new cap/rotor and get it timed properly with a timing light.

The whole distributor assembly is brand new. It may need to be timed though. Also the car is idling fine. If the timing was off wouldn't it idle rough?

Re: Engine sputtering

Me thinks you should check your EGR system or catalytic convertor.

Is there a nice layer of black soot at the outlet tip of your exhaust? (running extremely rich symptom) and the smell you state could mean your cat is clogging.

It is basically a screen that is like a bunch of honeycomb shaped openings coated with a metal compound that 'grabs' onto molecules of the 'bad' stuff and separates them from the other molecules.
The result is the 'bad' stuff turns to water so to speak. That expels from the exhaust or vaporizes if all things work right.

Now if your car is running rich, over time those honeycomb faces get coated with soot, not allowing the process to occur correctly. Then that sends the downstream 02 sensor into tilt mode. Combine that with a malfunctioning EGR, the ECU aint got a clue what to think. Richen? Lean it? What? And at some point all kinds of weird stuff happens.

Not saying that is your issue here, but something to consider.

Also if the car does a lot of short trips, your exhaust may be full of water. That will cause bogging due to all the extra back pressure, which will also confuse the ECU.

Modern exhausts somehow let the water expell from the catalytic convertor area without exhaust leaking out, but our cars do not. At my work there are numerous trucks that idle for hours at a time while running top lights, powering office printers and stuff, charging laptops, whatever. There are always water puddles under them near the cat on the newer Fords and a steady drip of water from the other brands. But no so on the older vehicles.

Pretty much got flamed for driving like a jackass and was told to slow down. And I'll be damned, slowing down fixed it.

Re: Engine sputtering

This is a really old thread, but...catalytic converter. If you're having this issue, run the car a little while at night, and then look under it at the cat and see if it's glowing red. That's the sure sign. Either way..the cat.

Good for that new Ghost guy for searching.

Re: Engine sputtering

There's no cat on this car. I actually got it fixed after replacing the computer. Methinks I'm going to sell it now.
