repairpal.com > Problems > Nissan > Sentra

The electronic throttle actuator (throttle body) can fail causing a loss of power ... start it studders like it is running on 2 cyl. then switches to 3 cyl. then to 4. but ... Throttle body replaced on my 2006 Nissan Sentra 1.8 engine. ... I Was going up a hill and I tried to speed up, all of a sudden my car bogs down and completely dies.

Check the transmission oil. Maybe it is about to change. Some models dont have the shift stick directly on to of the transmission, Some use a linkage from the shift lever to connect to the transmission. If yours is using linkages try checking them. They could be bent or worn off. Usually these linkages have plastic bush at both ends and they wear off with time, making shifting difficult.

V6 or I4 engine? xe = i4?
bad tranny.?
low or too high ATF levels.
clogged bottom filter before pump, (shifts hot?)
RE4 trans is 4speed electronic
RL4 xxx trans is manual only
this side of your tranny has a tag is it RL/RE4 or or 3speed.

3 speed or 4 speed the FSM show four A/T used then .
there are 5 tranny total then ,4 AT (1 m/t)
on car diagnosis varies greatly by type.
fluid checks (if electronic the Tcm blink codes (DTCS)
pressure checks. for weak pump.
that stall rpm tests.

check for possible vaccum leak/vaccum hoses/intake gasket/throttle body gasket.hope it helps.sheppardart6

this could be caused by several different things.check E.G.R.vave to make sure its not sticking.Check fuel system,start with testing fuel pressure then filter and pump check every vacuum line carefully to make sure there is no cracks or leaks.I assume your computer is not setting a code so that could possibly eliminate your MAF sensor.Let me know whats up and I will check back with you.If this does not work I have more answers.

CHECK THE CATALITIC CONVERTER , THAT'S WHERE I WOULD START! COULD BE STOPPED UP.

it sounds like the injectors are not opening up man.. replace the injectores and this should fix your problem..good luck keith....

that is a normal rpm for the nissan pickup (hardbody)

try running seafoam through your engine it will clean and can eliminate such problems
