Topic: WTF Prob w/ 05 Sentra 1.8S... Ready to punch a baby (Read 14401 times)

El Beefo · « **on:** September 07, 2009, 06:59:22 PM »

Ok so about 2 weeks the wife tells me the her cars acting funny and the engine is alot louder then before but no check engine light? I said Ild look at it as soon as I have time and i finally had time this weekend. First off, ride is a 2005 Nissan Sentra 1.8s automatic. Car turns on and idles fine and for the first minute on the road it seems to drive normal until you get to about 20mph. Engine starts getting loud as a mother fucker likes its giving it all its got but its barely moving. It strugles to go 35 and can only do 20 uphill. Its drivable as long as you feather in the throttle but if you mash in or go WOT it starts to bog... car seems to die then jumps back into it... then dies... then comes back to about 3,xxxrpms. As soon as you let off the throttle it runs fine again. I parked the car at home to check it out and when you rev it in idle, the engine is loud as fuck now. Not so much the engine but the intake growls like a motha now? Im also hearing a ticking from aroung the fuel rail? So I pushed the fuck out of the car last night on WOT and finally a CEL popped up. Just took it to vatozone to get it scanned and it came back as a malfunction w/ the 1st gear in the trans. WTF? Im guessing this was from me pushing it last night and I know this has to be an engine prob but what? Bad coil, injector, plug? I buy a reliable new car I dont fuck w/ and I get this shit. Damn it. any hewp? Thanx for reading.

Those POS's have cat. converter issues what will destroy the engine if not caught in time... Possibly the cat is clogged

Remove the upstream o2 and continue your testing...

Mother fucker... I hope not. Just checked for recalls and found nothing related.

Conceptz-X · « **Reply #3 on:** September 07, 2009, 07:08:05 PM »

Ive replaced 3 so far...

Sounds like a clogged cat to me. Just take off the exhaust and go for a quick ripper and see if it still dose it.

How many Miles on it?
I think the dealer is obligated till 8 years 80k now for emissions related repairs

Conceptz-X · « **Reply #6 on:** September 07, 2009, 07:10:13 PM »

cat is in the manifold take out the upstream o2

El Beefo · « **Reply #7 on:** September 07, 2009, 07:13:27 PM »

bummer, car has 130,xxx miles on it... Out of states trips to family. It would make sense but why no related CEL?

clogged cats are hit or miss, when they degrade in efficency and still flow well they will throw the code

Hello and thank you for using JustAnswer.com

I would look into a Mass Air Flow sensor. This sensor is known to cause drive ability issues and never turn on the Service Engine Soon light, cause it doesn't fail, it just meters air improperly. I would have the air and fuel mixture checked. If out of spec, then I would have the MAF sensor replaced. I would replace it with a factory one, not a after market. After markets never seem to work on Nissan's.

I would also inspect the air duct to the throttle chamber. Make sure that is secured properly.

unplug the maf and see if the problem persists. if it does, and i predict it will, continue looking into a new cat.

I havent seen any of the AFM's fail yet on that new of a model, but I agree with factory replacement on Nissan, 3 aftermarkets later on one job...

See if the throttle cable is adjusted right so that the TPS is going closed every time when you let off the gas. Also could be a bad knock sensor.

No throttle cable, electronic

patsmx5 · « **Reply #18 on:** September 07, 2009, 09:52:41 PM »

Ah. I got a POS 98 sentra that did just what your saying and it was the TPS sensor not always coming closed, and the knock sensor connection wasn't perfect.

That was because you didn't have your MS grounded correctly.

im not reading this thread but Iv changed countless coils on them.
change the coils, boots, plugs

El Beefo · « **Reply #23 on:** September 10, 2009, 11:15:28 PM »

Ok so i finally got an hour of free time to work work on the car whille the lil one was asleep. Pulled the O2 and its not caked up at all... just the norm light carbon? I did however order some MaD TyTe JDM headers on wednesday but now im thinking its not the cat only cause the O2. Car has gotten worse... now only makes it to 25 and it strugles to do so. Engine is getting even louder. Intake is most deff not clogged? Could it be the AFM/MAF? would it really cause probs like this? Engine feels like its running on just 2 cylinders and now im hearing a ping/rattle durring accel. Bad Coil? Gonna check the plugs later tonight if I get I have time. To late to call autozone... do/can the test/check coils. Fuckers are pricey even used. Dont wanna buy anything I dont need. Fuckin NisAnd because I'm an intellectual being, !

jagojon3 · « **Reply #24 on:** September 10, 2009, 11:19:43 PM »

The engine is getting louder as in it's revving higher? Is there a tach on that thing? Torque converter lockup solenoid if that's the case.

First person to solve the Prob is getting $10 via Paypal.

Joseph Davis · « **Reply #29 on:** September 10, 2009, 11:42:05 PM »

Since $10 is eclipsed by the time it takes to drive to you, no.
