I have a 2004 and every time I make a stop or put it in reverse it smokes alot with a strong smell of oil , while the car is running it doesnt smoke at all , also when I floor it the engines feel really weak , can some body tell me if a need a new motor or how can I fix this problem , Thank you

P.S sorry if my english is bad Im Puerto Rican

 

Can you tell us a bit more about your car? How many miles? Is it manual or auto? Do you have any modifications? When is the last time you had it serviced? And what was done?

 

Well I bought it from a female cuple months ago and it was already with the smoking problem , it has 88,000 miles , I have no modification what so ever its all stock the only thing moded is that it doesnt have Catalyc , and last time got services was October 2 from this month and it was only a oil and filter change I thought thats was going to help but it didnt

 

Does it smoke out of the exhaust pipes or around the engine?
Is the smell definitely oil or is it just rich exhaust from not having a catalytic converter? A car without a cat will smell worse than one with it.

If the cat was removed, it's likely it was clogged, which points to an igntion coil/wire/spark plug issue. Can you see with the previous owner exactly what had happened? IF the ignition coils haven't been changed in the last 20-30k miles, you will definitely want to have them all replaced. Likewise for sparkplugs and wires.

The best way to know your engine health is a rotary compression test (a regular compression test won't do). Usually you can get that done at the Mazda dealer.

 

Thank you, but I chaged the Spark Plugs a couple weeks ago and the wires looked really good ill need to take a look at the coils im gonna change them to see if it gets better and yes the smoke comes out from the exhaust
