ok nick i had a leak on injectors 1 and 2 going into block. I could actually hear it when i put my ear next to the rail. So i retightened and took for a lil ride. Huge difference. I even broke a lil traction into second and it went sideways a lil. I'm resetting the ecu and going to go run it tomorrow morning. I'm done cranking wrenches. I also noticed that the afm sense wire connection was a lil crappy so i respliced it. Man i couldn't believe my eyes when i saw the damn injectors spray and coils spark. Just freakin pissed me off.

compression on others were 3 = 1454 = 1505 = 1536 = 150

they're close. I know they're supposed to be like 170-180lbs but i'm thinking about doing a piston/cam/rings upgrade.

Yeah, if there's a leak, those cylinders are injecting lots of extra air, so the plugs could be white because they're terribly lean..dunno. But yeah, I had an issue like that before with installing my new injectors, the car idle poorly because it is essentially a large vacuum leak. Get the seals all straightened out and get the rail bolted in straight and tight and try again man, you're close.

My car is scary fast now, I broke loose in 3rd today just rolling on it

ok soo i have somewhat fixed the damn issue. There was an air leak at the 1st two injectors going into the block so i fix the rail and viola i have combustion. I had 1 cracked spark plug and that screwed me. I still back fire but it seems insignificant. She idles really well now. Just have to fit the recirc pipe back into hks ssqv fin for the pfffhew noise. Thinking about using silicone to seal vynl piping to hks ssqv outlet. Anyhow, it's finally over or atleast so i think. New clutch getting put in this week as well as new rim and tire. Thanks for all the help fellas.

Well last night was great. I finally got combustion on my fi.rst 2 cylinders. There was a huge increase in power and response. Clutch finally going out on me and it's hard to get it into 4th gear. Sounds like TOB is done. Finally i can rest at ease because it's working finally. Although she still backfires. WTF

NO SIR.. learned my lesson with that soo i rerouted it and it seems to work well but when the bov closes is when it happens. Shifting gears. or in a grear but at low rpm under 2500rpm and cruising. Think it might be this new damn 02sensor i bought from oreillys wich is the bosch universal 3 wire for the ca18det. Since i put that in it was backfiring like crazy.
