Hi,

OK, well so far we have a new MAF, and now new plugs, and 4 new O2 sensors, and now I just put in two new coil packs, and we're still seeing:

P1172
P0171
P0174
P0102
P0734
and six P1884's

Good god please help !

Cheers'
Dave

 

vacuum leaks?, injector problem/clogged?, fuel pressure?, bad ground???, sensor plugs not making connection?
just some ideas...a lot of codes = a lot of ideas

 

When you're clear the codes and run the truck what is the first coast you get?

 

Hi,

I did a scan yesterday and cleared them - I'll get another reading today .....
It stalled 3x's on the way home.

Yesterday

P0171
P0102
P1884
P1175
P1412
P0174
P1172

And this is with new plugs and coils packs and 4 new O2 sensors .....

Dave

 

Yea,

I was thinking that because there are some days where it runs happy as well but how do you
check for those ? I've ran some throttle body cleaner thru it and it just had a bottle of fuel injector cleaner two weeks ago .....

Should I look at getting a new short cable from the MAF to that plug on the block ......

When you say back ground ..... do you mean the battery?

Hi,

OK here the next set I got from today ...... driving along at about 50MPH.

I got ...

P0171
P0174
P1175

Parked the truck for about 2 hours and when I came out:

P1884
P0102

Cleared them again so we'll see tomorrow! Any suggestions or ideas?

Cheers'

Check the F2 fuse under the hood (15 amp)

 

HI,

So when you say check the fuse - just see if its intact ?
What is it for and should I just buy a new one?

It's been real cold here for the past week, and now not a single code has come up.

Cheers'
Dave

 

f2 feeds...purge valve, o2 sensor, maf sensor, crank position sensor.
I still say check connections, very well. check wiring loom around back of engine, too.


I find it interesting that it is cold and no problems.

 

Hi,

Yep, thats one word for it interesting .... the other one would be PIA. (grin)

You got me - it was intermittent and now that's colder -5 to -18 deg C no errors at all.

I'll actually replace the fuse and not even fart around with it. I did that with a relay once and it fixed some stuff too. The entire fuse box was replaced once by the local pirate dealer for +$1500 and they said it has to be done. Should I be looking for a crappy repair job and maybe do the fuse and check the fuse box in behind?

I'm open to suggestions ..... Massive Thankings ....

Cheers'
Dave
