Engine Performance problem
1990 Toyota Corolla 4 cyl Front Wheel Drive Manual 80,000 miles
This may sound stupid but I just want to know, when I'm at idle, not moving, my engine runs 800rpm but when I step on the breaks the idle rpm drops to 600 or 500rpm. Is that something I have to check with?
Second, I have a muffler and a resonator, I don't know if I got it correct, but it's like I have a muffler underneath and a resonator at the end of my exhaust. I want to just employ a downpipe exhaust but they say I will loss power since there will not be enough back pressure. They say my engine needs some back pressure to avoid losing power in long runs. Is that correct?
More power and regards,
have the same problem?
