Whats up everyone! Here's my problem. We were running low on gas, but needed to be somewhere quick, so long story short it ran pretty low. Not low enough to start puttering. The next day when i went to go get gas it started to miss if i tried to give it a decent amount of gas. I thought that it was running out of gas so i babied it in and filled her up. I only use premium by the way. The problem is still there. Its fine under normal driving, but if you try to pass someone or get on it a little it putters and wont go. Ive tried injector cleaner, heet (dry gas), and just filled up again and put lucas in. I stopped and got the codes read and here they are.
p0150, 0327,0174, 1174, 1415, 0155, 0135, 0302, 1319. I know most of them are miss fire and o2 sensor, just dont want to throw a bunch of money around and not fix the problem.
Any help would be great!
Thanks....

 

main problem isnt the o2 sensor. id be looking into the mis on 2 more then anything here... what year is the truck? if its a d1 you might have clogged up the fuel filter and just arent getting enough to the engine, but that doesnt explain the 1415 code at all. how much noise does the engine make when its out of gear? any popping sounds?

 

2003 and it idles fine. The ses was on b4 this happened so im not sure what codes were on there prior. Im going to go get the codes pulled again tonight. Could it still be the fuel filter even though its a d2? That was my first thought and then the guy at autozone said that it wouldn't be that. I'll pick one up when I go there. I just figured that it sucked something up and got clogged. No popping sounds by the way. A small exhaust leak from the manifold flange but thats it.

 

how many miles are on your truck? when was the last time you did a tune up? 8mm magnecore wires and some bosch +4 plat plugs? your exhaust leak is causing some errors as well.

d2's dont have fuel filters so dont bother buying one. dont let your fuel tank get that low ever you will burn out the fuel pump. it uses fuel to cool itself.

 

How many miles on it, has it ever been tune along with wires, what octane gas are you using?

 

My almost exact problem was solved by changing out the O2's... this stopped the rough idle and missing. I was getting the multi missing code as well as several different individual cylinders missing as well. I changed the wires, plugs and coil and still had the problem until i changed the O2 out.

Just my 2 cents.

Best of luck.

Regards,

 

I had a similar problem, intermittent low power, occasional (very) hard starts, low power on long hills/passing. Turns out it was the fuel pump.

 

Thanks for the replies. I've got just over 100,000 and the previous owner changed the plugs and wires right b4 i bought it. They're STI cables but I havent pulled a plug to see what he used. I never have hard starts, it just happens when I get on it a little. I always use premium 93 oct.

 

im just wondering if i should pull the pump and see if its restricted by something. whats the best way to depressurize the lines?

 

Leave the pump alone, I would start with clearing the codes and read them again after a short drive, pull the #2 plug and see what it looks like, color, moisture or smell.
If you still have the 327, you may be looking at replacing the drivers side knock sensor, replace all 4 02 sensors then clear the codes and see what if any come back.
