STALLING AT IDLE/ STOPS

2002 Jeep Laredo

Engine Performance problem
2002 Jeep Laredo 6 cyl Four Wheel Drive Automatic

Hello, thank you for your advise. Are there any tsb's on this vehicle that I missed? There's no MIL, no current/existing codes. Fuel press. Is 55 psi at idle. Rest press. Was 53 after 8 hrs. The iac was a little dirty, but not enough to cause stalling. Also, it has'nt been tuned up for 40,000+ miles. What is the spk. Plug gap? 4.0L SFI. I plan on using autolite AP985 plugs. Thanks again, Andrew P. Sobczak

.035 (In thousandths of an inch)

I would also recommend checking for vacuum leaks.
