Thread: My 95 Altima Running Like Crap

lately the altima has been running pretty weak . the idle is alil bouncy and the drive is just not that great . the CEL is on and i just recently pulled the codes .

the codes im getting .
33 - O2 Sensor
34 - Knock Sensor (Replaced)
76 - Fuel Injection System Failure
103 - Park/Neutral Position Switch
105 - EGR/Canister Control Solenoid (Replaced)

so far i replaced the EGR Solenoid and the O2 Sensor (Upstream) .

i also cleaned up the injectors but unsure if they were cleaned right . im currently thinking of replacing the injectors to see if that would help .

please help me with this problem .

BTW the distributor is NEW , the cap/rotor is NEW . Has NEW spark plugs .

EDIT
while researching some more i found out several things that may give me the 76 CEL .

Check Items:
-Intake air leak
-Front oxygen sensor
-Injectors
-Exhaust gas leak
-Incorrect fuel pressure
-Lack of fuel
-Mass air flow sensor

Do a compression test?

i dont think the compression is off .

bump made an edit .

Maf ftw

i have a MAF from a 240sx . should be the same ima try it out tomorrow .

UPDATE . i swapped out the MAFs . did the samething . but notice that when the MAF was unplugged the engine sounded normal idled correctly .

so im guessing it may not be the MAF .

Same numbers on the maf

no but interchangeble

guarantee you have a vac leak at the head to intake manifold connection. Very common issue with the paper gasket the ka24 uses. Spray some brake cleaner along the head to intake manifold connection area along where the gasket would be and see if the idle changes. If so, whalla.

you Vac strength is low so that may be causing the other emissions related issues.
