When the car is in its failure mode, have someone man the accelerator and listen at the tailpipe. Have the helper gradually raise engine RPMs and see if the normal muffled sound of combustion turns into more of a hiss.
If the catalytic convertor has failed, it may have lost chunks of ceramics that are clogging the rest of the exhaust system.

Please tell me the engine specification of Tata Nexon. Does it is coming in the automatic as well as CNG version in India?


Tata Nexon is the subcompact 4-metre SUV from the Tata Motors, which has created a lot of buzz even before its launch. I don't expect the Tata Nexon gets a CNG kit and it only offered 6-speed manual transmission. Here I specify some of the Tata Nexon specifications, have a look

=> It is available in both the engine. The petrol variants carry 1.2-litre Revotron which produces 110 bhp of power & 15-17kmpl of mileage while diesel have 4-cylinder 1.5-litre Revotorq engine which makes 110 bhp of power & 21-23kmpl mileage.

=> 6.5-inch touchscreen infotainment system, automatic climate control, dual front airbags & reverse parking sensors

=> Three drive modes Eco, City and Sport

My 2006 Ford F-150, V-6 engine, will start but only stays running for a few seconds, then bogs out. Battery is new.


A few seconds, or like 2 seconds. Is the security like flashing? The light could be a red dot on the top of the dash. Have the codes read, takes a scanner. Check engine light on when it is running, Also check the codes, code reader will do this. Does the engine just shut off or does it bog down, like sputter till it dies?

What's the sign of a bad cat converter on a 1999


If the cat is clogged, blocking exhaust flow, the car may start normally, and may run fine while the engine is cold. Within a few mins as engine warms it will start to bog down and die when you try to acellerate, even a little. May even die out if you give it gas, while it may idle just fine.
This has been my experice in 2 different cars of different types over the years.

I have a pontiac grandam and it want turn over or anything and I had the ignition and starter replaced. What could it be


It could be the security system...It often times masks its self as a starter ignition or battery issue....If this is the problem turn your key to the accessory mode for ten minutes...have jumper cables and another vehicle on hand should your battery die...This seems to be a common issue on these vehicles but if this is the problem it should start after leaving it on accessory for 10 min

Idle and hesitation while accelerating!!!


The simptoms you are describing sound like the catalitic converter, that will choke the car and potentally get better as the car heats up. advance auto will scan the car codes for free. a quick check is to start the car and check the exhaust flow out the tail pipe there should be a fair volume of exhaust gasses at high idle when you first start the car at cold.
