5d] Excessive white smoke from exhaust on cold start? Not that I am aware.
5e] Excessive black smoke from exhaust under hard acceleration? Sometimes
6] Performance Issues
6a] Do you have gauges (boost, EGT)?: Unkown.
6b] Maximum boost under load?: Unknown.
6c] Have you added a performance PCM (reflash) or Chip?: No.
6d] Have you changed exhaust / downpipe / crossover?: No.
6e] Wastegate – mechanical or vacuum (OEM)?: OEM. On my task to do list to replace.
List and describe any other factors which are not addressed in this checklist. We can’t see, hear, smell, or touch your truck, so the more descriptive information you can give, the more likely it is that somebody can assist you.
1. Sometimes when SEL is on I get sputtering on deceleration. This has just happened as of recently.
2. Coming back from Gulfport a couple of weeks ago, during deceleration letting foot off pedal truck kicked into acceleration without my foot on pedal.
3. Truck has randomly stalled while on highway. Not fun with semi behind you.
4. I have cleaned all grounds. I am starting to think I have a timing issue.
5. Did check for air in lines, none found. I did replace a cracked return fuel line on drivers side.
6. I did replace the Fuel Solenoid Shutoff on 5/20/2011. It was leaking. But I am not always hearing the click before starts. Wonder if it is getting stuck.
