Sputter after belt change

[icemaninlv]

So my power steering belt flew off....well I replaced it.
Noticed my coolant was old so why not do that as well.

Get it all done and runs like butt!

I have a data interface with ecu talk and no codes.
Pulled CAS and all injectors are firing. BTW they are brand new less than 500 miles

PTU S2 with new wiring is brand new, along with all filters and plugs. all coils read 1.2 ohms while #2 reads .7

only thing I touched was the PTU wiring when i did the belt.
Might need to do the hard wire soldering.

feels like running on 3 cyl under 3k rpm, then flys afterr 3k.

was running rich prior but not to bad. CTU is fairly new 6-12 months

any other ideas?

Okay did a power balance test and no change when #1 pulled plug from COP. getting 6.33vdc on the plug itself and 1.0 - 1.2 ohms on the coil.
all the other coils read 4.4vdc

from what I read it looks like it should be 12vdc

I never had the luxury of the consult but I can tell you that all the cop's should read the same, if one of these things isn't like the others it's likely bad. Did you unplug COP's with the car at idle to determine if in fact it is truly idling on 3 cylinder and which ones are not working?

it just feels rough like 3 cyl.

The only one that acts up is the #1. now....my voltage test were good now as i was measuring when at idle.

I swapped out my ignition relay and it ran fine for 5 minutes then acted up, don't think #1 is working will work on it later.

well i changed the plug out and adjusted the timing via an extension plug instead of the black loop near the PTU and it runs like it did before. I know this thing can be faster. Everything is running like it should but I really feel like it's down around 150hp instead of the 230. IDK maybe it's just my mind.

The N/A 2+2 was the biggest, heaviest Z32 they made, apart from the vert. I thought my 2+2 was quick till I got my TT. It was made to be a fun cruiser, not a go fast machine.
