Engine light goes on and off
Car has almost 50,000 miles. It will be running fine
at 50-60 mph, then engine light goes on, it starts to
run rough, sometimes stalls and I have to floor it to
go 40 mph for 2-3 miles. Then I start to take my
foot off the gas and it speeds up and runs
smoothly. Engine light has gone off. Weird.
...guessing the oxygen sensors before and after the catalytic converter are getting plugged...must check the intake temp sensor IAT (a small wire that contracts with cold)~ these can burn out and the ECU doesn't know what to do (rhymes)~ ever change the air filter or spark plugs...bout time for a replacement timing belt and tensioner~ do you maintenance...and you will not have a plugged converter~
