Elantra stalling coughing shutting off.?
2001 elantra. Replaced every sensor,(EVERYONE), purge valve, fuel pump, and filter,p.c.v. Valve. Plugs wires, coilpack.O2 sensors. Charcoal canister fine, but car still runs great sometimes, then bam! Stalling, coughing, loss of power, total shutting off, starts sputtering. Had it to two garages,of course it did not act up then, and all the computer said ,O2 sensor bank one. If you disconnect battery, then start the 'check engine light stays off for about 5 minutes, or one mile, then back on. As I replaced each sensor, the damned thing ran no better, and no worse! Made no difference whatsoever! Weather, and temp. seems to mean nothing! Runs like dog dirt whether in or out of gear, even in park,and neutral. Tranny isensors new also! Gas cap on or off, no difference! I mean I tried every trick in the book! Even garages couldn't find it. I bought it and a few days later it starts this,and I am stuck with it. Everyone says what a great car these are; could've fooled me! Anyone have any answers, solutions?d me

Feel your pain dude. I want to add an idea cause you've replaced most of the things that may have very well be the cause(s):
The temperature switching between hot and cold may have effect some of the electronic components on your vehicle as I've seen from time to time. Things like the CKP (Crankshaft Position sensor) or the ECM (Engine Control Module) Etc. The CKP is easy, most people just replace it if wiring is checked out good. This is the trick that only professional does from time to time to check the ECM for the effection of temperature changing:
Warm the ECM with a hair dryer set at low heat, keep the dryer moving all around until it warm (Not hot) to the touch then install the ECM and see how it run.
Take the ECM back out and put it into the refrigerator until it cold 35 degrees or so and install it and see how the car run with a stone cold ECM.
Whatever The ECM reacts to the temperature change and show the symptoms you have described with your car: You have found the cause of the vehicle problem: It's the ECM ! ...Go to your dealer for replacement and program the new ECM .
Send a message if you need more help. I'll reply. The shop's Foreman just call me on the PA, have to go and see what they need my help for. HTH
