Hello! Please forgive the length I’m trying to be thorough.
My 99 Toyota Corolla has been stalling pretty much as soon as the engine heats up. It cuts off abruptly I lose high power things like steering and braking but dash lights stay on.
Eva 02 and cat sensors were showing on error codes.
It’s almost like clockwork how it shuts down. It’s very abrupt and I can’t start it again until it’s cooled all the way down to the point where the temperature needle doesn’t move at all. All these problems started when I put a little bit of steel wool in a hole in my muffler to silence it. I have as far as I know had the catalytic converter and O2 sensor lights on for a long time but it hasn’t stalled at all until I did the steel wool thing. What’s odd is that I didn’t put a lot in there just enough to plug the hole. It stalls every single time within 8 to 12 minutes of starting.
I also have a high idle (1500) when I first start in it hardly ever settles down below a thousand.
After it stalls I can crank, that’s no problem the only problem is it doesn’t turn over.
My RPMs don’t seem to have any effect on it stalling sooner or later.
I can’t emphasize enough that it doesn’t sputter or do anything aside from just die.
My battery is pretty old but I’m pretty sure my alternator is good though it may have some sporadic issues.
Because people at car parts places have been suggesting an exhaust issue compounded by an electrical problem and because my car just today started throwing crankshaft sensor codes… And this is a brand new problem. It starts up fine if it’s cold no problem at all so I don’t see how those could be related as they weren’t there at all the 100 or so times it’s stalled after warming up before today… but I thought it’s worth mentioning.
As far as some electrical anomalies that I’ve been having I’ve been starting my car occasionally with a much higher current deep cell battery as opposed to jumping it from another person’s car whenever it would run out.
You could say the problem is the car itself but Im far from Rich and I feel like there’s a simple problem though maybe two…
Any help at all is greatly appreciated and thanks for reading my novel of a post!!
