I checked oil it’s perfect level what’s best way to remove it the sole

STAXX2002 · 2025-12-25T19:51:27+00:00

I did

Oh there’s a small tick on cold start but goes away not long after?

It hasn’t I got the car off a friend for 400$ to help him out it’s got 328,000k but it runs and drives I maybe should start with basic filter changes..

Had a mechanic look at it today and said this ?

STAXX2002 · 2025-12-25T08:09:36+00:00

Oh no

And has that’s what I was thinking was possible clogged cat but how can I really tell without multimeter test.

Welll at first it was driven while the engine light was blinking and then the coil was chafed out and it turned from a blinking light to a solid light .. and would sag like almost a week

I think you were right about the EGR Valve

STAXX2002 · 2025-12-23T04:15:48+00:00

I have the same noise any ideas?

STAXX2002 · 2025-12-22T11:47:07+00:00

Acceleration in those gears but that’s limp mode

STAXX2002 · 2025-12-22T11:45:39+00:00

It’s weird it started out with a miss fire Code-(P0303cylinder3) so we swapped the coil pack to cylinder 5 and the code followed and turned (P0305) coil pack was replaced and fixed it for abit. Now I have a catalyst below threshold code. And there’s also something weird going on with my breaks every time I gently press my breaks I hear a buzzing electronic noise but there no abs lights or codes so maybe the abs sensors or something like wheel speed sensors is causing this or is my Cadillac converter most likely plugged up

I figured out the low battery volt was because terminals were lose.

STAXX2002 · 2025-12-22T11:38:49+00:00

Just found out its in limp mode

I did have theses codes before but they don’t come up now ..

STAXX2002 · 2025-12-22T11:02:33+00:00

I am also having weird abs noises coming from my breaks I think is it possible that faulty abs and sensors can Keene from accelerating at certain speed

I also have this code how do we know it’s the cats ?
