engine check light???

[mikegtdyno]

My engine check lite went on, I put my actuator on yesterday, could that be the problem???,,some tell me Its my downpipe but ive had that on for 3 weeks now....

Check the code you are throwing. Turn ur keys to on and click on and off (without actually starting the car!) After about 5 tries you should show a code beginning with P

[NYYDYNASTY]

based on your mods in your sig, i assume you're still st.0?

in that case, you might have thrown an overboost code (I think its P1188).

how do i do that?? and how do i make it to p1188--- its confusing

[NYYDYNASTY]

as hozay said ... stick your key in the ignition. Turn the key all the way, but don't turn the car on.

turn the key off and on 3 times. watch the dash. after about 3 times,you'll see codes display where the mileage was displayed.

and then im done all i do is that??

[NYYDYNASTY]

yep .. once you see the code, write it down and turn your car off.
thats all you need to do.

then post your code, here

[TopOfNewYork]

mike you need stage 1 if you dont get stage one you are gonna have to keep disconnecting your battery to take the code off

and another thing you have that wastegate to tight and you are boosting more than normal

Thats a negative bro, I have had the wga on my car for over a year now and never threw an overboost code, I took off the red line (ed tip) going to the upper pressure pipe and never threw a code. The code I bet he is throwing seeings as though he has a downpipe (assuming no cat) is P0133 (downstream rich code) I get that every now and again, but I rarely have to reset it, it comes on and goes off all by itself. I have been driving my car now without the code for a week now, I am sure it will come on soon.

P2074-MANIFOLD PRESSURE/THROTTLE POSITION CORRELATION
- HIGH FLOW/VACUUM LEAK

Thats what your code is telling me, sounds like something is up with your MAP ot TPS sensor

okkk what should I do??????should i leave it alone or....

[Screamin Demon]

No, first off, you need to do a boost leak test first to see if you have a leak, if you find that you don't have a leak anywhere, you need to check your sensors to see if they are not faulty and messing up.

ok, im not like genious wiht engines but would one of the sensors be the one that the red wire was connected to on the intercooler pipe

[Screamin Demon]

I believe if I am right, the sensor you are talking about is the IAT, but that could also be the one on the intake. THe MAP is the one on the Intake Manifold, right on front in the middle, the the TPS is either the one on the intake or the charge pipe, someone correct me if I am wrong.

[mikegtdyno]

im hearing a zzzzzzzzzzzzzzzzzzzzzzzzzzz noise from the fuel line that conncts to the fuel rail is that normalll????

[mikegtdyno]

hold on i saw a sensor thing disconnected if u look down past the radiator hoses..........i re connected it and my car still ahs the engine light on

[Screamin Demon]

The zzzzzzzzzzzzzzzzzz noise could just be vibration on the fuel rail, but it could also be a bad injector. Disconnect the battery (just the negative side) for 5-10 minutes, that will reset the computer and then hook it back up, if the check engine light comes back on, check the code again like you did before and report back up.

the cel will stay on. you're gonna have to disconnect your battery for a period of time. then reconnect it.

this will reset your codes.

[mikegtdyno]
