This weekend I changed out the injectors to other stocks one since I was having leak by causing misfire and high EGT. I swapped out the injectors and also while under I double checked all connections.

I went to start the car and it wouldn't start, but it did turned over, dumbfounded I found that the CAS sensor had come unplugged even though I didn't touch it (Damn elves...) anyways I put it in and it started up but I instantly noticed the misfiring and the lack of power. Could this be the main issue?

Car will not boost and it feels like I am driving an NA, I looked over all the hoses for a leak checked the PCV system and cannot find anything. I have a power FC and checked the sensors and the AFMs are showing roughly the same Volts and did a check on those, TPS is sitting at .5V and I'm pulling 20 deg at idle, checked injectors

I check everything and still scratching head, but all help is needed. Right now I need my car on Sat night/Sun Morning but let me know if you can help.

Copy all. That was the thing I was looking at the TPS. Now how would I go about reseting it? I know that the idle voltage should be .5V, but is there anything else I should look at with the TPS.

For the CAS, with my Power FC I'm sitting at +20 deg at idle, but I can advance the timing to 25 and it will smooth it out, I had checked the plugs and they were gapped correctly so I think it might be the CAS as the engine cranked but the CAS was unplugged...damn engine elves...

I'm at work but I will check it out today.

They were second hand out of a running GTR my friend has. He upgraded his and I was there when he pulled them. The car ran fine with them and we just switched them over.

Tried to start it again today and it was still misfiring. Pulled the injector harness for each one to ensuring firing and all cylinders are firing...

Okay, after one cigarette (I don't smoke) and a redbull I cracked into it...and I found that number two injector was dead, like whitney houston dead. Swapped that out and I am still getting misfires, but ran better. Tomorrow I'm going to check the coilpacks and see if one popped on me. Also the sparkies too. Got to love this though. I'm driving around my car sounds like a boxster... :(

      It's sodium citrate, I misspoke earlier. It's a citrate buffer solution. And yes, depending on how thin the metal in the tank is this may or may not be a wise decision but if it's just mild rust it should clean off and it should be fine.

      Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
