I was driving home today and my car started stalling and jerking at 2500 rpms so I pushed the pedal down a little more. This only caused it to jerk more so I let off the gas a little and it calm down. I shifted thru the gears noting to stay away from 2500. I went about 1/4 of a mile and had to stop at a traffic light. I left the light and got about another 1/4 mile before I had to stop because it was obvious at this point I was going to be on the side of the road so I choose my own stopping place. It got where I could not even make it to 2000 rpm, then 1000. I pulled off the road and it shut off and never cranked again. I happen to have my OBD 2 with me so I pulled it up and checked my codes. I had the beloved P0171 and P0174 codes. I've read the other post people are posting, but I think mine is a little different in that it would not crank, as if it was out of gas. (I had over half tank) I've had a idle issue with this car for years. 5 yrs ago I took it to one of those Euro Fix places that kept it weeks at a time trying this, trying that. I remember they "re-coded" my car, changed the plugs, wires, cleaned the fuel injectors, etc, and never found the issue.
Recently I took the DISA valve off of it and checked it from the steps I've learned online. It checked out ok, but I noticed the O-Ring wasn't tight when I took it out so I bought a new O-Ring and replaced it. I cranked it up and it seem to run fine for a day or two, then started the rough idle again. I think I was just wishing that was the problem. What it will do is when I pull to a stop at a light or stop sign (5 speed) and idle it will 'chase' up and down the rpm's, sometimes settling on its own. Most of the time I have to give the gas a quick stomp to 2000 rpm and release before it settles down without going up and down. There have been times where it would shut off as soon as I crank it and it would take MINUTES of spinning before it will crank again. Those Germans know how to make a starter if nothing else! When this happens it acts like it was starving for fuel. I can smell it and it stinks. I always run 93 octane gas. weird. I often wondered if it could be the catalytic converter, but it runs like a rocket when I hit 3000 rpms.
I'm at a loss and pretty discouraged at the moment. It acts like it isn't getting any fuel. Could a faulty fuel pump, regulator, fuel filter be the issue since it won't crank? I
would love to hear your related stories or experiences or if you have any ideas to try first. I don't want to be one of those that replaces everything from the front of the car to the exhaust pipe and still have the issue. Thanks for reading.
