Car riding rough

[2kdb7]

I did a compression test a few months ago if I remember it was like 117 119 119 121. I rented a tester it was like $15. The seals should be good I redid it the day before the test along with a valve adjustment and the tune up. I saw a video of a guy doing the timing on YouTube and he said you have to jumper the ecu to time it rite could that be part of the problem?

could be a clogged cat

X2 my previous GSR did that for that reason, found out only after 500 dollars was spent on about every other possibility. After running cat at night look at the cat if it's not cherry red disregard.

So...it was the spark plugs... -_-

I seriously didn't think it was the plugs since it wasn't throwing any codes, but there was something telling me it was the plugs so I bought a new set of NGK plugs and it runs fine now.

This is after I cleaned them.

It was probably because they were E3s. Some cars don't handle those well. My dad's jeep does fine on them.

So it's still making that putt putt sound every now and then, but it's not as loud or frequent and the struggling to gain speed is gone. Probably has a bunch of crap inside the engine from the bad plug and I gotta wait for the seafoam to clean it out.

Let me know how that works I'm so tired of it messing up

sorry didnt see that you changed to ngk plugs. I only saw the E3 ones. When replacing parts, go with OEM recommended parts.

So after telling my mechanic friends and grandfather that I have a k&n air filter they ALL unanimously said "clean your mass airflow sensor." Apparently the oil from the filter contaminates the sensor and you have to clean it every so often? Gonna try that after work.

Good luck finding the mass air flow sensor bro. They are ALL unanimously wrong. Your car does not have a MAF.

Seriously? Then what is the sensor on my intake manifold that says "Sensor MAF"? I'm confused lol

Thats your MAP sensor

 

[Nick_C78]

Theres a TPS, MAP, IACV, IAT sensors on your throttle body and intake manifold. No MAF. Is the one you are looking at on top of your throttle body? If so it is the MAP sensor with a "P" not an "F". Which stands for Manifold Absolute Pressure I believe.


Just curious, are the mechanics you talked to ASE certified?
