tII runs rough during accel, timing maybe?
 

I finally got my tii running after i found my problem with the cas, now its running rough.

the car has been sitting for a while so i put in good gas too see if that was the problem but it ran a little better i think.

it idles fine, compression is good, brand new spark plugs, i was messing with my cas when i was fixing it. is it a timing problem maybe?

any other suggestions, at first i saw my coupling from my turbo to the afm was loose and i tightened that but i couldnt find any other leaks.

thanks

also it overheats, and i have coolant in there.
i have an oil leak but idk if that would do it.

What do you mean you were "messing with the CAS" ? If you removed it and then put it back in without lining up the timing marks, then yes, that will screw up the timing. Look in the FSM for the proper way to reset the CAS.

Overheating is going to be coolant related. Do you have an e-fan? If yes, how is it switching on right now? It may just be set too high. Give more information on what your exact setup is.

i had an efan on there but i took it off and put the stock fan back in.

and i filled it up with coolant, and it still has all of the coolant in there.

it doesnt overheat but it gets real close to the max heat mark.

also my spark plugs are brand new and i ran the car today for a couple of hours and now they look destroyed.

ill post some pics of them in a few, if anybody has any ideas lmk.

the first one is leading the second is trailing, all of them look like this. leading looks like its kinda burnt and it has an orangish brown around it and trailing is just grey.

these are brand new btw.

also the car kinda just gets stuck around 3900-4200.

could it be my secondary injectors not cutting on?

i got on it today, after i filled it up with good gas and fuel system cleaner.
and the car just fell flat on its face, it feels like i have a vaccum leak but i dont, i sprayed carb cleaner on every vaccum line.

it idles kinda rough but still normal and when i floor it the car sputters and it takes forever to get into high rpms.

what is this the symptoms of?

could my injectors be clogged?
my afr is reading normally though.

A tan color is normal.

Have you compression tested this engine? If it's good, you should start by pulling engine codes to see if anything is acting up.

Also, if you're reaching the top of the stock water temp gauge, that is very bad. Normal operating temp is about 1/4 the way up on S4s. Does the auxilliary e-fan come on when you see it overheat? It is set to come on at ~207F from the factory, and will give you an idea of what temp you're really seeing.

im going to do another compression test soon, and my rtek is saying my intake temp sensor is bad but i eliminated it when i built the engine.


and the fan use to come on but now it doesnt anymore, and the idiot lights is showing up the cooling fan light

i pulled the lowerspark plugs and when i pulled out L1 it had metal shards on the top opposite of the tip.

so im sure its safe to say my engine is blown
