My 98 isuzu hombre w/ about 130k on it started running really rough and would stall when it came to an idle as I was driving it on the freeway the other day. I limped it to the nearest service center and the only thing they could tell me was that cylinder 3 was not firing. The list of codes they retrieved from my memory were as follows in chronological order: P303-miss cyl 3, pending..., P0172 rich bank #1, P0303 Miss Cyl #3, after clear... P0300 Random miss.
Each cylinder metered at the following: #1-140, #2-145,#3-0, #4-120.
As I limped it home, it continued to run very rough and after about 30 miles it started to make a loud clicking noise which sounded to me like the oil lifters. So I pulled over and put 2 quarts of oil in, but it continued to make the clicking noise. I fear that this could be the piston rod or something.
Does anyone have any ideas? The garages I have spoken to about it are very hesitant to do any head work on it so I need to get an idea of what could be wrong so I can know if it is worth getting it worked on or if the engine is toast and I should just sell the piece of ****. Thanks
Cracked spark plug, damaged worn plug cable, the clicking, thumping is a result of operator forcing engine to run out of synch, as result of electrical combustion loss. the fact the vehicle continues to run rules out any problem with fuel line - fuel components. Let us know the outcome please.

4cyl or v6 must be the V6 as the I-4 is OHV chain the V6 is covered the 8th digit of the VIN answers this 4= 2.2L 4 cyl. chain cam OHV w= 4.3L v6 ,chain x= same but tad diff, v6. chain there is no belts this year. yes confusing its not really an ISUZU with belts its a CHevy S10, with a silly Isuzu badge
no engines codes, is not true i bet ,
some codes take 1 to 3 trips, or dont store
and if you get CEL glowing, driving too much can clear the codes.
so.... that means you must scan it failing. see?
sputtering is misfiring (bad spark or way to rich fuel)
why do you jump all over fuel first.
try spark FIRST no gas engine burn fuel right with bad spark'
not one, and is first not last.
ever heard of tuneup, done one in last decade.
you know, spark parts? plugs and wire top list.
in the rules of basics its:
engine good, (compression test pass, and vacuum looks ok)
why do that backwards/?
If you've not done anything to your truck, check the Clutch master cylinder under the hood, there is a resivoir that should have brake fluid in it. It usually sits next to the Brake master cylinder & is a smaller unit. If nothing has been done to the system recently, and your fluid is full, either the Clutch Master Cyl. or the Clutch Slave Cy. mounted on the bellhousing of the trans. is defective, or has a leaking connection.
If leaking connection, tighten & bleed the system. Check under the clutch pedal on the floorboard for brake fluid, if you find it, the Clutch Master Cyl is the problem & will need ot be replaced. Otherwise, the Clutch Slave Cyl. will need to be replaced. System has to be bled after replacing either & the Clutch Master Cyl. must be bled before hooking up the lines to the Clutch Slave Cyl.
probably the throttle position sensor,but also could have jumped time.i would take the T.P.S. out and check the resistance,i am not sure what the correct resistance is for that model but you can find out at the parts store.
you dont need to ground your ht lead, infact that could damage your ignition system, if in fact removing it from the plug does make it worse you then know that this cyl was firing and that ignition on this particular cyl is not your problem.
