Sure do.
They're in great shape!
So what are you suggesting? Swapping them back in to see if that's causing the problem?
What else should I be checking?
Also, when. It's running, I can't tell if I hear an intake leak or if it's just the engine sounding like shit due to misfire. I sprayed carb cleaner around the vaccume lines and intake, no effect on idle...
I removed the fuel rail again and swapped #1 injector with #2 and reinstalled everything.
Also I read somewhere to reset the PCM by holding the negative and positive batt cables together for 30 secs. I forgot to turn headlights on and off to finish PCM reset. so I think all I did was reset CEL.
Here's a link to that:

I started the Heep back up and No CEL yet, but still runs like a fat chick (horribly). Just as bad as before.
Negatron. Weird that it didn't pop up when I ran these codes today. I just ordered both 02 sensors and will replace them this weekend.
Tomorrow I check spark plug/wires and anything else you wise strangers suggest.
Shall I do a compression test? Fuel pressure test? I'm just shooting in the dark at this point. I blame ISIS.
Hey, sorry forgot about this thread. Wise strangers do that though.
Yeah that second injector from the left is toast, throw that in the round file.
Personally I would go to my local boneyard and find some out of another Heep. However the others look better than what I got and my engine has 186k and is running good.
How many miles are on the bottom end of engine?, I know you put a new head on but didn't see anything about mileage.
Compression check would be a good idea, fuel pressure check would be a good idea, checking wires and making sure there in the proper location would be a excellent idea.
O2 sensors are really important to, anything obd2 relies on them heavily. One thing I would like to add about o2 sensor replacement is, if the vehicle has a lot of miles on it or even age can be a factor IE: almost 20 years old, you may want to consider there is a problem w/ the connector's.
"Universal" 02 sensors come with a new connector for the ecu side and the new sensor(you'll be putting on a new connector in other words), but that's time consuming to install, I prefer to just butt splice them on. That way you know the connection is not a issue.
Also, from what I've noticed with my 2k disconnecting the battery is a bad idea, it gets angry!. Runs like crap low power, mileage sucks, starts hard blah blah. I know when you do disconnect the battery it takes a long time for the o2 sensors to re-arm themselves which is why it runs crappy, you got a 99 though so maybe different, lots of changes in 2k.
Either way not having a cel w/ the complaints you have sucks! you basically are just shooting in the dark, how do you know where to start?
Check the compression, put new wires, cap and rotor on check the routing. New o2 sensors(just cut the plugs off and butt splice them, that's hi performance!) and let everyone know what happens:cheers:
