holy typing skills... sorry i'd help if i understood, really i would.

 

wow man that would really suck if after you spent all that money and replaced all those parts it was just a wiring problem. in fact just take your car to a real mechanic before you waste any more time and money.

is the check engine light on?

 

it could just be that one of your injectors is not firing. do a compresion test if you bought a used head.

 

Typing was a class I didn't study for. lol

 

Yea man, the engine light is on. But worst comes to worst I'll probably put a whole new engine.

 

k now wait i have a very similar problem. im assuming you did the mpfi conversion? how are the soldering joints for all the injector wires? double check them! also...if this is happening all the time you can check the injector (mine is soo random so i cant) ..when you know! its not firing, take a screwdriver and put it to an injector thats working first....you should hear a clicking noise..then put the driver to the 4th cyl injector and see if it sounds the same. Im betting on either an injector or an injector wire. Now, you know how to check codes right? find out what code your throwing!

 

The injector got replaced and still she doesnt love me, I was curious why the smoke was a light blue so I removed the 4th sparkplug turned the car on steped on the gas for a second turned the car off and found the cylinder where the sparkplug goes in slightly covered with oil all the way to the top of the valvecover. I know this is serious. What else can go wrong?

 

maybe a bad ring ...hmm i would check your compression first off--but it sounds like you should just get a new motor if you were already considering heading down that road.

 

dude stop replacing parts. if the check engine light is on that doesnt mean put a new engine in.

where is the oil leaking in?
how much blue smoke?
do a compression test
wat code is the check engine light for
do you know how to read codes?

 

Is your valve cover leaking? Do you have spark on the #4 cylinder? Are you sure the injector is good? Switch the injector with one from a different cylinder and see if the #4 is still not combusting.

 

blue smoke prolly means bad rings, had same problem with my mpfi conversion, save time, rip it out and start over, or buy an si harness

How would an Si harnes fix his problem? Everything you need to do has been mentioned.

And go from there. My money is on the wiring in the mpfi swap, probably code 16. Start tracing wires.

it's probably either wiring or engine internals (rings, burned valve, bad headgasket, cracked block, etc.) Before doing anything else, get a compression tester. Harbor freight sells them for under ten bucks. That will tell you if the engine has internal damage or not by measuring how well the piston is compressing the air.

Also, try the screwdriver trick. An injector can be good (if fact, they rarely go completely out) while your wiring is fucked up.

Don't use an si harness. It's nice to have some of the plugs, but adapting it to work in your car is a bitch.
