Question about 2004 Nissan Sentra 1.8

1 Answer

We have changed out the catalytic converter and the car ran great for just a couple of days. It is now not going over the speed of 15 miles/per hour what is our next troubleshooting step?

At first the rpms revved up really high and did not go over 55 miles/hour we got it diagnosed at Car Quest and was told that we needed new catalytic converter. We replaced it along with a new VSS now we are back to square one any input!

If the plugs and wiring are ok! Try changing the fuel filter. A clogged up filter will bog the car down, and it may also quit at stops. No power on hills ETC. God-Bless you! and your family.

I have a 2005 gmc envoy xl the rpm's are real low and it wont go over 15 miles per hour


Could be catalytic converters clogged. Remove the pre O2 sensors, or loosen the exhaust at the manifold. If it goes faster, replace the cats. Have the codes read.

My grand scenic well it will not pick ip any speed the most I get is tem miles per hour and its very juddery. had everything imaginable changed now im told it must be ecu please can someone help me


sounds to me light your catalytic converter is worn out. is the car hard to start? after starting car put your hand or a towel over exhaust pipe. if hardly any exhaust is coming out I am willing to bet its your catalytic converter. i had the same problem 3 years ago but my car would barely go 30 mph and was slow to acelerate too.

Can a bad catalytic converter cause the ignition coils to go bad


A bad catalytic converter can cause your vehicle to run rough and even seem to stall and hesitate around 40 to 50 miles per hour, this will feel like a ignition problem, the simplest way I found to check a cat is with a cheap infrared or temperature probe, check Amazon or Ebay, they are inexpensive enough, you don't need great accuracy , nothing expensive. The tempeture of the cat after the engine is hot will be approximately 30-40 degrees hotter on the output of the catalytic converter than the input, also the exhaust will have an odor of rotten eggs.

its most likely a catalytic converter issue. they are usually only good for 10 years, mileage has no bearing on their lifespan. the precious metals inside wear out over time, not miles. in many parts of the country where we dont have smog tests most folks dont even know they have a failed converter untill the dang thing falls off the car.

Sounds like the catalytic converter is plugged. Remove the oxygen sensor and check the back pressure.
