Partially clogged or engine misfire.
A catalytic converter can turn red in a 1990 Cadillac Seville due to excessive heat, often caused by a malfunctioning engine or fuel system. This could result from issues like a rich fuel mixture, misfiring spark plugs, or a clogged exhaust system, leading to increased exhaust temperatures. Additionally, a failing catalytic converter itself can contribute to overheating, further exacerbating the problem. It's crucial to address these underlying issues to prevent damage.
by wackin it ;)
there isn't one
YesYes
loss of power.noise rattling from exhaust
Not sure but a 1991 model does, so it stands to reason that a 1990 would.
This light is indicating a emissions problem or failure. The catalytic converter may be operating at low efficiency which is a sign of failure.
AnswerCrawl under the car. You will see a muffler, and a catalytic converter which look similar. The converter is the one closest to the engine.If it's a 4 cyl. It should be between the exhaust manifold and engine pipe.
I am assuming that you want to know where the Catalytic converter is in your 1990 Cadillac. it is underneath the car, silver color (or rust) welded to the exhaust pipe about the center of the front seat floor.
Because it liked screaming at your mice while it was shirtless.........
You can tell if the catalytic converter on your 1990 Lexus LS 400 is bad by noticing a few signs. Common symptoms include a significant drop in engine performance, a strong sulfur smell, or a decrease in fuel efficiency. Additionally, if the check engine light comes on, it may indicate issues with the catalytic converter. You can also perform a heat test, checking if the converter is excessively hot on the inlet side compared to the outlet side, which can indicate a blockage.
It sure did, That is the law on all makes and models.
