So a while ago i got the car starting and stopped there but i really need driving again.
Sooo here it is, the car is hard to start and when it does it barely idles and wont idle if i take my foot off the pedal, runs a max of 30 seconds. The problems i know so far is that i have an upstream exhaust leak and possibly a bad o2 sensor. I'll be testing for vac leaks once i get a buddy to help me spray. Any ideas?
 


What injectors are you using, do you have the proper IFR table in the pcm for said injectors, and who did your pcm? Does unplugging the maf and/or 02 sensor help at all? Can you hear any vac leaks while it's running?
 
Zzp did my tables but i just got my tuner so I'm gonna go over everything, unplugging them did nothing and i couldnt hear the leaks but I'm gonna get carb and check anyway
 
Can you try swapping your original pcm back in? If not, just write a stock file in for your car and go from there, that way you eliminate the tune being a possibility. Make sure you have the right IFR table for your injectors, and pull up your dtc's (they don't always set a cel) see if you got anything. Double check your plugs/wires, make sure they're all fully seated and going to the right cylinders (**** happens). Might check the ICM ground and make sure it's good as well.
 
injector table are good, plugs are seated at the correct position, ground is okay, no fault codes when i scan, tried the original pcm with no luck, tried the l36 crank pulley and it runs the same

needless to say I'm puzzled
 


No luck with vac leaks? Did you scan your 02's to see if they're switching to rule out a bad 02 sensor?
 
I found my problem and it was a very stupid mistake i accidentally knocked the crank key in and now i cant find it... Oh joy
