Jeep Strokers

so. i have a 4.6 stroker
here is what happened.
about a month ago i got my jeep up and running again (it sat for 4 years) had issues with aftermarket cam and timing, finally figured it out and had her running great.
in the process of figuring out what was wrong i replaced.
crank position sensor
fuel pump
fuel filter
fuel pressure regulator
all injectors are new Bosch mustang injectors
i was driving her. and the track bar had somehow came loose. i had an awful death wobble, i pulled over into a nearby parking lot with a misfiring engine and checked out what happened. nothing in the engine compartment looked out of the norm. got back in started her up. check engine light was on #12 #27 and #55, i tightened up the track bar with tools i had with me. and started getting home. she is misfiring at low speeds and high, got about a mile to the gas station. turned off the car. and started checking any wires for burns. the o2 sensor wire had wriggled its way close to the header. but only the wrap surrounding the wire was melted not the wires inside it. i moved it away from the header with a ziptie. started her up. everything was normal. no check engine light. no misfire nothing. so off i went home. i stopped again about halfway home (10mile drive) turned her off, then back on. all problems back. misfire and check engine light. got her home called it a night.
heres my thinking.
o2 sensor may need a new wire just in case.
#27 cel means fuel injection system. so i bought a noid light. all wires are working fine. does this mean bad injector ? how can i tell which is bad is there a way ?
#12 is troubling because why would the battery be disconnected ?
ive been tinkering for 2 weeks with no luck. checked timing to make sure it was correct. it smells like gas if i hit the throttle at all. cel is gone. but problem still exists.
im trying to think what could be wrong. the whole engine shook pretty violently when the death wobble happened.

im not to familiar with obd1 codes but you o2 sensor controls the fuel mixture so that might be your fuel injection code and a bad o2 will make it run like complete crap what is #55?

#55 is just end of codes
then that may be it. but in my thinking, okay big shake right. it ran like crap immediately after the death wobble. so. it wouldn't be instant that that wire was burned through. what leads me to believe its something else.

o2 sensor wire replaced. it wasnt even really melted but barely on the outside of the wire casing. but replaced. still runs like crap

Do you remember the Stroker running great over 4 years ago or did it have problems then? Why did it sit?

First things that come to mind are:

Distributor not indexed correctly.
Incorrect injectors or Fuel Pressure
Ground Issue
Cam lobes wiped out
What's your AFR at idle and with a load?

the car sat while the motor was built. and life happened. as it does. I put the motor back in in December, had issues with timing due to distributor needed to remove ears. I had it running perfectly. before the death wobble. and it ran fine after momentarily which leads me to believe something electrical
injectors are all brand new and should be correct
since it ran fine for a moment afterwards i think we can eliminate cam problems
Wednesday or Friday im going to do a fuel pressure test and check all the fuel lines for damage. I have already checked timing and its correct.
sorry but how would i test the air to fuel ratio ?
at the moment. the car stalls out at idle every time. and it smells like gas. i have pulled every spark plug just to test them. all seem to fire fine.

If it smells like fuel then its probably getting way too much fuel. When you pull the plugs do they smell like gas and wet? Maybe your injectors are stuck open...

Measuring AFR is critical to the success of a built engine. You need a Wideband 02 sensor and a gauge to read the output (or computer if you wish). Many companies make them. I personally like and run the AEM kit.

i will look into buying a air fuel ratio tester.
in the meantime. if i pull the fuel rail and crank the engine wont i see if the injectors are spraying too much ?
also. check engine light for #27 is gone. but still runs like crap

noticed something today. header to frontpipe gasket looks like it is not sitting correctly. bought another gasket, ill re-seat it tomorrow. this would make sense tho. engine code. everything. shake must have pulled it out of place. with an air leak there could mess with o2 sensor correct ?
