Engine Performance problem
2001 Nissan Sentra 4 cyl Front Wheel Drive Automatic
----------------------------------------------------------------
Hi I am working on a 2001 sentra with a 1.8L with automatic trans. The car wont rev over 1500 rpm if you floor it, but if you ease into it you can make it redline. The motor is getting plenty of air and fuel and it has spark(at least at idle) and the exhaust is not plugged. The tests I have done are; fuel pressure test(41psi at idle and jumps to 47psi when given throttle), disconected one by one the coil on plug, all drop the same at idle, pulled an o2 out to see if the exhaust was plugged. The only thing I noticed was at the maf sensor there are three wires corroded. I ohmed them and all were less than 1.0 ohm. I have replaced the spark plugs with ngk laserplatinum cuz they needed it anyway.
