Well I've been having issues with stumbling on acceleration. I had the issue before and never got it resolved so I parked it for a while and I'm messing with it once again. Starting off this time I changed the spark plugs, rotor, cap and wires. I also drained the tank and replaced the fuel filter. That did nothing. Then I removed and cleaned the EGR and checked it and it was good. No change. Then I put in a new FPR and it didn't change anything. New Airtex E2000 and no change. The thing is that I can, and I know it's not suggested, put my vice grips on the fuel return hose and it runs like a scalded ape. If I run it without that it won't even pull itself out of a ditch. I hooked up the reader to it this evening to check some live data and found that my STFT and LTFT were way off. STFT was about 25 at idle and LTFT was about 20. LTFT fell to 0 once I revved it up to 2500. It bogs then drops. I believe STFT went up to 32 at the same rpm. I haven't checked fuel pressure yet. I guess I'll go buy a gage set up tomorrow and try and check it at the rail. This engine is in my Samurai and I don't have the sidekick filter installed. Thanks for any help you can offer.
