hey guys. im new to this forum. i drive a 2001 honda accord Coupe EX V6. i have a K&N cold air intake along with a Greddy cat back exhaust (give u some general engine specs there ;D). a few months ago i had to replace the whole transmission. i have a few problems. i notice a burning smell when i smell the grill area of the hood/front bumper(dont ask me why i smell my car haha)...also my car sometimes shifts on its own from first to second but most of the time i have to let off the gas in order for it to shift. and finally, this happens once in a blue moon, my engine randomly revs without me revving it. the CEL came on the first time it happened, and the code was P1399 which is a random cylinder misfire. i plan on putting it in the shop soon but are any of these immediate concerns?

 

The burning smell your probably smelling, is your radiator... Was it a new transmission you replaced it with? How many miles on this tranny? Im not sure on the engine code, but im sure someone will chime in...

 

it was not a completely new tranny, but a rebuilt tranny. maybe 4k miles on the new tranny. so the radiator....fluid? or a problem

 

could the burning smell be the fan's wiring?

 

the smell was just the burning of the armor all i use to clean the plastics in my engine lol my bad....i just always use that and i guess ive never smelt it before. still not sure about the code and revving. hasnt revved in about a week but when it does its very randomly

 

anybody have any answers for the revving? the engine code is P1399 which is a random cylinder misfire. should i take it to a shop?
