strange things

[rob28]

ok then
new VSS installed
8 new plugs installed
new plug wires installed
no change, and still pulling obd2 codes p0304, and p1316 out of diagnostic system
would a faulty injector cause this?
do they fail often?
any ideas what might be causing this problem, it seems to be getting worse too.
way strange because the thing runs great except for 4th and 5th at about
2000-2500rpm, odd

 

[rob28]

any ideas? anyone? anyone?

Fuel filter or fuel pump is possible.... injectors could cause this on an older vehicle.... Carbon build up on the exhaust valves is another possibility...

 

[rob28]

is 1996 considered older?
I'll do the filters next I guess
then go for a cylinder #4 injector change
let the games begin
thanks

 

[rob28]

changed #4 injector, no joy
would a knock sensor cause my issue?
sea foam huh?
funny, I live on an island!
anyway, fuel filter tomorrow, we'll see

so far
new plugs, wires, vss,cylinder #4 injector, and tomorrow fuel filter with a smoke session ala seafoam in tank, block, and intake (plenum)
I think I might clean the MAF too?

1996 disco SE7 5spd 4.0 green w/tan interior 73,000mi

rovers rock, learned how to drive in a 1957 land rover
things were a lot less complicated then

talk to me joey!

 

[rob28]

one more thing
P0104
P1314
P1316
what does Injector circuit IDM codes detected mean?
every thing is pointing to bank 2, yes?
thanks, and happy holidays

I have a scan tool
and I have an interface for my laptop to view sensor data real time if that might help
long term fuel % is a match.short term has a big split between bank 1 and 2
the rover does not smoke
starts good
Idles nice
when I got it, I drove it across three states
no worries at all
drove it here on the rock for a long time on premium gas
then one day, shifted into 4th gear, and it was as if I dropped a cylinder
shifted into 5th same thing
right about 2000 to 2500rpm, at about 50mph, but not on a downgrade
1rst 2nd and 3rd, all good
***?

 

[rob28]

new fuel filter, seafoam session, no improvement
no rover dealer here in ketchikan alaska
hmm
any more ideas?
anyone?

 

[rob28]

ok then, back to my chevy shortwide
no sensors
damn
I have so many parts coming my way
I want this thing to run right
my dad's last ride
I will not stop
chevy is a thing that always gets me there
rover is a money pit
it runs
but it does not run right
I am sure it is something stupid
I will figure it out

 

[rob28]

what would a rover owner clean a MAF with?
DNA
MEK
BRULIN?
JOY soap?
or?
