Well today I noticed that my "92 F150 4x4 w/ a 5.0 would like hiccup when traveling at 55 mph. Almost like the power was there then gone. It started idling kind of rough also. I pulled the codes and got these:

327: Evp/Ept Low
538: No Wot / INVAL CYBAL
536: BOO Open (due to not pumping the brake during testing I believe)
632: O/D Cancel Switch (due to not engaging during testing I believe since it works fine)

I recently replaced the cap, rotor, coil, wires, and plugs. I did all of that in the last two weeks. Yesterday I cleaned the IAC. I pulled these codes using my OTC 4000e code reader. Any help will be greatly appreciated.

check the gas cap see if its on tight my truck has done that before and it was the damn gas cap

AuroraZero

That would **** me off royally lmao!

No such luck bro.

TheCollector

yeah thats a common probelm with f150 owners they forget to tighten the gas cap. try some fuel enjtor cleaner you might have has some bad gas?
does it do it constantly almost like a tick or just random?

AuroraZero

First time it has ever done it. Was pretty consistent at 55. When I went up 60 did not seem to bad. Also only happen when it is warmed up. Hence why I thought the IAC needed a cleaning.

On a side note bro do not leave your truck unguarded in Michigan. I want those fender flares lmao!!!! Would cover up a lot of my rusty spots lol.

TheCollector

yeah alot of people want my flairs and i honestly do not like them they came with the truck. but its covering up some rust on mine. this summer i should be getting some fresh metal on it and off comes the flairs

you do have an odd problem it just does it after 50 mph but if its rought idle check your spark plugs? its usualy something simple check the new cap for a crack or something? check the egr or cat for build up that cat needs to heat up so that could be something to do with that.

Done both and no change. I am wondering if I got some water. Bought some at a Wesco I do not usually go to. I put lucas fuel treatment in it. Maybe that will help.

You sell those flares you let me know man. Mine is getting new skins also and hopefully I can find a flare side box as well.

yeah gas is getting more exspencive so the shady gas stations are losing money so they cant keep up on tank matanace. and ethenol i beleve is hydroscopic? it has mosture in it and attracts mosture so any place with 10% ethenol could do that i used staybil ethenol treatment everyother tank full water+engine=
youll be the first to know LOL then the other 10 people on here then the 3 at my shcool

AuroraZero

Better yet take measurements for me and I will build some lol. I have nothing but time anymore bro. Yeah could be I got some water and if I did I am going to smack the crap out of the people at that Wesco lmao.

TheCollector

right LOL demand free gas for life. ill take some mesurements for you when i got some spare time probly this friday check your air box for water if it has rained out latly as well that could do it too
