ENGINE LACKS POWER (4AGE) 1600 CC, 4 CYL, TWIN CAM
From a dead stop engine runs as if it is running only on 2 cylinders. I have automatic transmission, when it is in "Park" or "Neutral" it runs fine, but in gear, engine severely lacks power from a dead stop, once you get up to about 20mph engine starts getting stronger, ran codes and code given is "all systems normal". Don't know what to do totally confused? Car has new fuel pump, also replaced shift solenoid in transmission cause my car was starting out in 2nd gear instead of 1st. When driving, my car wouldn't downshift all the way to 1st gear only to 2nd. So when you would take off you would be taking off in 2nd gear but that shift solenoid was fixed.
I had the fuel pump recently replaced i just assumed the fuel filter was replaced also cause my fuel pump is in the gas tank. My air filter is clean and I have 4 fuel injectors, no carburetor. A friend of mine who has looked at my car for me says it sounds like there is some kind of air leak but can't figure out where it is coming from?

Lets start at the beginning. I'm going to assume it is a V6 engine since a 4 cyl would not run on just 2 cylinders. The injectors on each bank are wired together, so they all open at the same time. I'm going to ask how you know those cylinders are not firing ? If they were really dead, the vac gauge should show it with a shaking needle. And you should have a puffing sound at the exhaust pipe. You said the engine is new - did it ever run on all 6 cylinders ?
This car doesn't have coils and wires, it's gasoil. The most likely reason is the piezo injectors are worn. The best way to test is with VCDS After an overnight stationary period drive the vehicle with cold engine between 1200 - 1600 rpm till the complaint occurs. Constantly read the measured value block 13 and 14 for the smooth running control in the engine control unit. The values of one or several cylinders should noticeably move to positive.
modified injectors A8: with 3.0l, 4.2l TDI from: WAUZZZ4E*7N016685 Replace the injector with the highest deviation and all injectors produced between 1.3.2006 and 30.4.2006.

no, the plug is firing. But the timing is off. the plug is firing quite a bit before top dead center on that cylinder. The burning of the fuel mixture is occurring while that piston is on its way up and is slowing it down---dragging down the whole engine. i think you should change the distributor cap and rotor as cylinder one is firing at the same time as cylinder 2or 4. This indicates a possible carbon track in the distributor cap.
Unfortunately, your question is very vague and hard to understand.
16 or 32 cam? Usually your engine will have twin cams, or single cam. Overhead cam(s) or not. You could determine if your engine is a 4 or a 6 cylinder, and then you will generally find out how many valves the engine has.
If you are in a 4 cylinder car, you probably have 16 valves if you have a twin cam engine. If you have a single cam, 4 cylinder engine, then you will usually have only 8 valves.
The only way that you could end up with 32 valves, is if you have a dual overhead cam, v-6 engine. Each head will have two cams, and each cylinder will have 4 valves then.
I hope that this is what you were trying to ask. :)
it sounds like you may have the wires on the wrong coil. It should be #1 on the #4 coil, and the #3 wire on the #2 coil. you probably have them backwards so 1 and 3 are firing on the exhaust stroke. the firing order is 1-3-4-2. they should be hooked like this.
depends on engine code, and single cam or twin cam. check your code. D16W4 sohc stage 1. 29nm stage 2 72nm. D16Y5. stage 1 20nm. 2. 49nm. 3.67nm . 4. 67nm. there are 2 other codes for sohc engines these are the same as D16W4. DOHC engine as follows B16A2 stage 1. 29nm. 2. 83nm. hope this helps, if you are ot sure give m the exact engine code and i can verify.
