You could have a vacuum line knocked off or with a hole in it, sure. Make sure the distributor hold down bolt was tightened (if equipped) and that the timing isn't jumping around .

if this problem 'just started' i would say to double check your belt timing marks, one tooth wrong could cause this.
if it 'might' have been there before the job, i'l tell you how to check the 'codes' to see if something else might be wrong

let me know

Also recheck your vaccum lines.. MAP sensor may be unplugged..
If I remember, you posted a question elsewhere about replacing a timing belt, procedures if the belt had broken??
How does the truck idle?

yes, that is how you count the codes, the flashing light(it's an all GM system) the wire should be loose in your left foot kick panel, three wires into a white connector with about a foot of slack, ground the two outer pins with a paper clip. i don't actually remember the sequence of 12's though, i've only used a scan tool on that connector, if nobody else answers before monday, i'll check the service manual in work. from your description, i bet you have code 44 'lean exhaust' i can also tell you the oxygen sensor from work(the dealer) is about $240 list for a regular a/c delco sensor, take the isuzu 10 digit part number, drop the first and last number and you have the gm part number, but i guarantee you can find it much cheaper elsewhere, you probably should stay with a/c delco, just my opinion though(can i still say that?)

Yes, change any pitted lines!

As for the sensor, if you get the AC Delco part # from www.acdelco.com you can probably source it cheaper than a GM or Isuzu dealer can sell it to you. Should be the same part.

Mike: Of course you can state your opinion. LOL!

one sign of black smoke is its too rich or fouled plugs,also if your cat is giving you a smell it might be clogged

Geez, I hope they fixed the problem before now; this thread is 5 years old.
