My 2001 nissan sentra doesn't have alot of power until after it warms up. it won't even go up a hill. What could be wrong with it?

your ECM/ computer may be shot. those model sentras had campaign, where the ECM box would be lined with foam to hold the computer tight, but the fumes from the glue that Nissan used to hold the foam down, would eat the computer internally and destroy it. Nissan had us pull those foams out and discard. if you still have the foams inthere, good chances are that the ECM is fried, causing issues. Question: did you use aftermarket air filter in the air box?? or Nissan filter?? Let me know. very important to use Nissan filter it this car.

replace ur crank/cam sensors. without a proper signal form those ur car will turn over forever without starting.

Check to see if something is jammed in it

Skip compression test, the results will be misleading. replace the head gasket on this series of Sentra. The first symptoms are that it take slightly longer to starting when it has been shut off warm for about an hour

check for spark/fuel/camshaft sensor/crankshaft sensor/coil pack/check engine with scantool for fault code

replace the fuel filter it is clogged not letting gas pass through this fix it

Distributer Signal Output is code p1320........Intake Valve Timing Control Position Sensor Bank1 is code p1140...

ITS just run in you silly person as the normal engine (the heart of the car) will do about 200,000 miles and still go strong ...But you dont have to drive like a mad man just look after it and it will serve you well ..

I have 2002 Nissan ser with 120k, and I noticed a different temperature change when I start my car up...it takes a while to get warm. The weather has been cold lately, but my car has quick jolt as I'm driving until the car warms up. What is this issues I'm having...?????

~lopez:
I had similar problems after getting my ECU replaced.
later i got a letter from nissan saying it was the wrong program they flashed on the ECU (think it was a maxima ECU they flashed into my sentra)
it only seemed to do it right after my car warmed up while i was slowing down (for a stop) but never cut out when i was at a complete stop.

you can call nissan to see if there are any recalls or updates for your ECU program (they should be free if there is)

if that does not work, or it cuts off while accelerating, try checking your fuel/air ratio, spark plugs, air filter, and fuel injectors. (a fuel filter can even cause cut-outs as well if it's seriously clogged, but it's usually hard to start as well)

kinda sounds like heat problems, check to make sure your temp gauge is working and see if this helps...
- when it cuts out on you, turn key all the way off, then turn it back to full on (but don't crank) this should let you rad. fan run without cranking your car. if this causes the wait time to be shorter before you can crank it again (less than an hour) then it's most likely a temp gauge, water pump, hose or even a belt.
