It sputters

[02nightmaregt]

Ok so since i had such great help (seriously) on my last problem i now need advice again. So while i was driving home for the 4th (im stationed in NC and live in IN) i was driving through the mountains and was going up an incline and started to accelerate but the car started to sputter and bog. I stopped and refeuled thinking maybe it was just bad gas, and started driving and i was fine for about an hour or 2 than started doing it again. Im back in NC now and its fine driving normal but when i give it more gas than normal it bogs and sputters. I recently seafoamed it, changed the oil, and cleaned the MAF sensor. I have no idea.

SPARKPLUGS! Especially if you just seafoamed it you fouled them out even more.

Great. I was hoping that wasn't the case. Well i'll just get new ones than. While im at it what plugs would you recommend.

If it helps these are the codes it threw p1237,po133,po153,p1131, and p1151

p1237 - fuel pump secondary circuit fault

off the top i know the other four are slow respose and lean codes for banks 1 & 2, i'm guessing your fuel pump is crapping out and maybe causing a lean condition but that's just a guess

I forgot what brand spark plugs that i got, but i got them from Walmart. I bought the copper ones, gapped em, and they have been running like a champ for the past couple thousand miles.

Fuel filter is clogged or fuel pump is failing. SeaFoam does not "foul plugs".

Pull a plug and look at it if you do not believe me.

I originally did not think it did either. But in numerous threads i've read on here people say it does and to change the plugs after seafoaming it.

I agree that it is best to SeaFoam just prior to oil change or plug change to eliminate any chance of contamination. But I think the risk is very low.

For the p1237 code you really need a ford scan tool where you can run a KOEO ( key on engine off) self test to see if this is a hard fault or a Continuous Memory stored code. If it is not present in the KOEO test then the fault is intermittent and then what you would do is monitor the FPM pid and watch the reading while you shake the wiring and tap the fuel tank ( this simulates road shock) If the value is 75% and stays there then that is the default the Pid will read while the fault is present. at other times it will read 50% or will move between 85 and 115%

The other 4 codes are slow response and sensor lean codes for both front 02 sensors. The car is probably running lean while the fuel pump problem is happening causing these other codes.
