ok so yet another problem....
ok so yet another problem.... today was the first day ive driven my car since i soldered in the new coilpack connector from the main harness. everything seemed to be doing fine but as im driving home from work id give it maybe 3/4 throttle and id feel it sputter at 2k rpm and then shoot back to normal? it was like a sudden loss in power for that moment. could solering the wires cause any sort of current change going to the coilpacks and then cause them not to have enough power to make a good spark? i did a good job soldering or at least it looks good its not a big glob or anything its a smooth straight line with good penetration. and then i shrink tubed each one. then the other thing i can think of is maybe my plugs? theyre platinum/irridiums and only have 6k/7kmiles on them and i dont know why they would cause a sudden sputter at 2kRPM? what could be happening and how can i check for it?
ive ruled out bad gas as i just put in new gas same 93 premium ive always been using from a differnt gas station...one thing maybe i just thought of, i just installed some of Speed Inc high flow fuel rails with the install kit did it all correctly everything seems fine maybe because im using stock injectors and fuel pump theres not enough pressure in the big *** rails? or something is clogged in an injector? bad injectors? the problem really feels like the problem i just had with my coilpack connector pins being damaged and causing my car to loose 1,3,5,7 cylinders but when that happened my car threw codes for coil circuit malfunction and now im not throwing any codes but am sputtering...which leaves me thinking it must have something to do with the fuel system.

ok so AGAIN im throwing codes p0356 0352 0356 0358....all coil circuit malfunction codes....when i replaced the connector for the coil packs for at least half the day i drove it the car was fine and then towards the end of the day it started sputtering and now it threw the codes again and runs liek absolute ****. when i tug on the wire harness from the pcm going behind the motor it seems to affect the way the car runs itll slightly die or bog and then itll jump back up and just run like ****. there are no broke or damaged wires as i pulled the entire harness to inspect them when this happened the 1st time and that wouldnt explain why when i put the new connector on the car ran perfect until a few hours later....wtf is going on? im really starting to think its something in the pcm ive heard of limp mode, could that be it?

ok checked the grounds and theyre all there and tight. now what i tried doing today was replacing the pass side set of coils as i had another set laying around. it worked! for a lil bit. problem went away and didnt come back till about 20 minutes of driving...it slowly came back, sputtered once then more and more then the check engine light came back. what the hell is going on seriously? seems like i replace one thing everything goes ok till a little driving the problem comes back. the only thing i can think of is somthing is somehow shorting out? maybe ruining my coils? but all fuses are good and like i said in an earlier post i pulled the entire harness to inspect wires and they all looked good. man im gonna get *** raped if i bring this to a stealership
well seems today like it is now the passenger side coil connector on the main harness side that is to blame! why my connectors are randomly goin bad? i wish i knew. seems to me like the female pins arnt making good contact with the male pins causing me to misfire. i dont get why this is happening to me and why other ppl havnt experience this but thats another thing you can add to GM's shitty quality list...each connector costs $70 from a dealership, i already got the driver side one... for the time being what i did was pull out the female pins from inside the connector and pushed down on the part that is supposed to grab onto the male side and so far its working. im not gonna get my hopes up as this seems to be a freak problem that wont go away...
