99 TJ Sport Stalling Issues
I have a 99 Sport (inline 6) and she stalls at weird times. Did it today on the highway at speed. All of the sudden while holding a steady pressure on the accelerator she coughed, died and then roared back to life. The "Check Engine" light came on (still on). I cleaned the IAC, took her out for a test drive and she did the same thing again, but this time there was about 2 minutes of her wildly going from stalled to full revs back to stall, tach bouncing all over the place.
Troubleshooting so far...
1. Cleaned air filter
2. Better gas brands
3. Cleaned IAC.
I'm open to any suggestions on troubleshooting this.
Remember: 'Peon' used to be a verb.
