Loss of Power now

[ED6_BlackBeard]

Hey guys! This car is getting the best of me lol. My issue with the car is it is has lost power and it's lagging from a dead stop. The other day I opened The Hood and there was oil all over place and it got ucked into the intake and into the throttle body. I cleaned everything I could get too. I tried seafoam down the TB to clean any excess oil and carbon. Kinda helped with hesitation. The car was sitting over The weekend and I know I have an oil leak, so I added a quart. I looked at the plugs and the plug in cylinder 3(one second closes to the dizzy) and it's all fouled looking. I do know that oil seeps into that plug tube. There isn't a cel light but the ecu blinks 16x. I figure I'd try to get new plugs, pcv valve and possibly a new hg. But not really sure what I can do right now. Any comments would help. Thanks

I replaced the dizzy cap, rotor, and new plugs. Kinda help a little but still lacking in power through out the gears. I'm gonna see if my neighbor can do a compression test at his shop tomorrow...

When have you changed your air filter and fuel filter?

[ED6_BlackBeard]

When I first got the car few months ago, I replaced the fuel filter, spark plug wires, spark plugs. I washed the intake filter, but probably gonna need to change it. I recently just changed the dizzy cap and rotor, and got new plugs (others were fouled bad). Everything was driving fine before, I had oil being sucked into the TB. I tried cleaning it and also cleaned the IACV. The dizzy is even in full advanced. Could adding too much oil cause the HG to fail and cause it to have low compression? I couldn't get my neighbor to do a comp test, so I'm gonna have to buy one. Is it even worth fixing or just swap the head out for an A6? I Kinda want to keep it dpfi since it's my daily. I know the head will work, but would it be possible to use the d15 dizzy with A6 dizzy ignition coil? Couldn't find anything on that.

OK, so I been trying to figure out why the car was driving poor. With the ecu blinking 16x but No Cel light on dash. I figured it's the fuel injectors. I check the resistance with a dvom. Top reading = 10.56 Bottom = 10.59.. looking at the Haynes manual, I know my readings are way off. I'm not really sure why the resistance is way off. Any technical advice would help me a lot since this is my only DD.

Injector resistor?

[ED6_BlackBeard]

The ohms resistance of the dpfi fuel injectors. Am I supposed to check it while the car is on or off?

[Sandman]

I'm not sure if a dpf engine has this(It should though since it's still pgm-fi), but a resistor on the drivers side firewall. According to the manual, the resistance between the top left terminal on the connector and the rest of the connectors should be 5-7.

[ED6_BlackBeard]

OK, I'll try to look for that tomorrow. But if I'm not having any luck, just gonna take the car into a shop..

Nope, no resistorbox on DPFI setups.

so if you know that oil seeps into the plug tube, why havent you pursued that? Is it the valve cover seal? or is it the o ring under the rocker arm assembly? Is the plug itself oily, or is it just the part of it in the combustion chamber? If there was oil everywhere, then you need to find out where its leaking from. a bad valve cover gasket can definetly cause that. and oil covered plugs can very easily cause lagging. (wow... it almost sounds like i learned these things the hard way! )

Thanks guys, I figured it. Guess the loss of power was due to the fact that it had too much oil. So I drained it all out, let it drain for a an hour or so to get as much out as possible. Also found out that my oil plug threads on the pan were stripped. Fixed that with a size 14 self tapping plug and got that squared away. The car is back to running better. I think it mite need to get the ignition timing set back to factory. But other than that, I'll be OK for now. Thanks again guys.
