Engine Mechanical problem
1997 Honda Accord 6 cyl Front Wheel Drive Automatic 298000 miles
Someone please help me.
I have 97 accord V6 2.7L. I have 298K miles on it. First RPM was jumping when I am driving so I changed the ignition coil, that fixed that but after that I noticed when I put my car to warm up for min or two the RPM going up and down like I am giving gas but I am not even in the car it doing it by itself and this was winter time, now its summer looks like problem is fixed by itself. Now it is summer it does not do that now I have new problem I just started getting this code P0170 and P0171. So I changed the fuel filter, sparkplugs, wire. Tune-up. Still same code also same problem after tune-up and filter replace now car is doing crazy thing car runs ok for while but 20miles or so and then if I turn my car off and start my car back up it stall and most of the time it would not start it take me 20-50times (I blowup my starter doing that now I have new starter and I don't want to blow that one up) before I can get back up running and when I do getting running it will stall and wants to shutdown but I keep pressing gas and it will slowly very slowly start running at same time I would hear some kind of knocking noise from under the car where convertor is( I left the driver side door open I heard it that’s how I know this noise) after that noise is gone car runs like nothing happened. I am thinking it might me MAP sensor or O2 but it might be something else. I need help please help me.
