i just come back from a 1500 km trip,
After like 2 hour running i notice that my car was "missing fire" like if it was the lockup engage and disengage, but it was minimal miss.
First i tought my tranny was going out, arrived to my destination i let things like that.
The day after i took my car to go see old friends and when i start to move( like 1200-1500 rpm) it was missing just a little again. So ive decided to give it a try at WOT ,..
at high rpm i was clearly "missing fire"(dont how call it in an other way) and i noticed my boost was a little bit lower, and the car was feeling like i had the stock pulley...slower
(it happen to me earlier at high rpm while doing a run on quarter mile, but not frequently)
ive changed my wires before the trip thinking that it was the problem(missing on drag)
That same day (on my trip) i noticed more several miss , still between 1200-1500 rpm on small load and at WOT.
next day (today) ive decided to come back here, the car start good, smooth idle , but again when begin to move it miss , but very minimal miss,
the thing is that as long as i run it became worst and worst, at 2000 rpm with minimal load it was ok, but when trying to pass a car , the car shifted earlier in 3rd because it was like i released throttle.
anyway i continued my run and i got to climb a big hill and needed to pass a truck, so i open throlttle between middle and WOT was ok but as soon as i got in boost it was beginning to miss again and when ive looked back a huge dark brown smoke was going out of my exhaust...
At that point i was hoping no hill and no car to pass, 2 hour later im home .
Can it be the fuel filter? i hope
ill begin with that tomorow.
Any help will be appreciated.
