UPDATE!! with codes. Please Help!! My Car Is Acting Up? Dont Know What It Is?

[ryno]

My car is running really bad starting this morning, it starts to lag and stagger whenever I hit 2500rpm or more. It also has the CEL on, I cant find a boost leak. It did this a week ago, but went away until now and all i did is just removed positive connection on cable and reinstalled. Not so lucky this time. Can a bad connection to battery throw a CEL, cause its shi**y. The weird thing is it runs like a champ when CEL comes on like 1/4 of the time, even hit boost, but really shi**y the other 3/4 of time with the CEL. What is that about? I can also sorda smell gas when I drive. The weird thing is that my car just ran like a raped-ape for abouta week. WOW!!!! long time

3 codes were obtainedWTF Do you have any idea what this could be?
the codes read as followed:

trouble codes:
P0300 random / multiple cylinder misfire detected
P1104 manufactuerer specific powertrain trouble code

pending code:
P1104 manufactuerer specific powertrain trouble code

freeze code:
P0302 cylinder 2 misfire detected

Do you have any idea what this could be? Because I know nothing about what they mean.
thanks for the help in advance

go to autozone and get the code pulled when it comes back

That means your getting constant misfires, if the code keeps coming back and your car runs like crap, theres your answer. I would pull your spark plugs and check and replace them, as well as your wires, and hows your timing??

 

[ryno]

OK, I was going to replace plugs, is timing hard to check?
Also the selenoid valve is all crappy and was gooped togeather when I bought the car. it looked like the goop was falling apart so I redid it for now and the CEL came right off. Would that throw a CEL and cause my recent problems?

What is the "solenoid valve"?

According to the shop manual, for P0300, P0301, P0302, P0303 and P0304 the following should be checked:
*Ignition coil;
*Ignition power transistor;
*Spark plug; and wires
*Ignition circuit;
*Injector;
*O2 sensor;
*Compression pressure;
*Timing belt;
*Crankshaft position sensor;
*Air intake;
*Fuel pressure; and
*Crankshaft position sensor circuit and connector.

Not sure about the 1104.

mi vote is for the crack positon sensor or the cas

Check the wires coming from the front O2 sensor for melting. Bad O2 signal = lean mix, no O2 signal = rich mix. If it ran really well, it may have been running a bit lean. Now you smell gas, you're probably running way rich because the signal is completely interrupted or the sensor itself is toast.

OK. today I noticed that when car is at a stop and I go it will pull like a mother fu**er still seems really fast, but right as I get to a constant steady RPM and hold it for over 5 seconds, then that is when it starts to shake, studder, vibrate, lose power, etc. And the CE#L is still on at all times.

Please help me fix this.THANKS.

Do you think it could be plugs and or wires?
I might give that a shot, but would they throw a CEL?

Why don't you use that list i provided up there and check each item?
