Power loss

[dking]

My 92 XLT starting having power loss while driving, setting at stoplights and setting idle while in park. The engine revs up after the power loss. I replaced the FPR, fuel filter and fuel pump about two years ago. I have not pulled any codes yet. I was thinking about cleaning the MAF with CRC Electronic Cleaner. Will this be OK to use? Any ideas what could be causing the power loss?

Should be ok. Check fuel pressures.

Just checked to make sure that there was no vacum leaks and found the vacum hose had come off the FPR. I hope this is the problem. Don't understand way it would come off. I'll post again if this corrected the problem.
Thanks for your input Roadrunner.

Truck seems to running ok now. Still going to check fuel pressure and put a clamp on the vaccum line.
