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

I would also recommend checking for vacuum leaks.
