any sugestions as to what this might be caused by? after stalls sometimes wont start till sits for awhile. no codes in computer runs and idles great when cold

HELP thank you:runaround:

Fuel in the oil could mean excessive leakdown. Check fuel pressure and leakdown first. Key on, engine off and cold, fuel pump running; pressure must be 58psi to 64psi and must remain above 53psi for 3 to 5 minutes after the fuel pump shuts off. Post your results.

Turned out to be a leaking Fuel injector/ spider replaced changed oil van runs like new no problems now

Leaking injectors will cause leakdown to be excessive. Good job, glad you got her fixed, and thanks for posting back.
