I have looked around on here trying to figure out this problem. I did the throttle body cleaning and changed the 02 sensor then reset the CEL. Monday the CEL comes back on and the car starts spitting and sputtering. I go get the Codes checked and this is what I get:

P0300 Random cylinder misfire
P0171 Fuel Trim Bank one condition
P1133 Heated O2 sensor bank 1 sensor 1 insufficient switching
P2135 and I have no idea what that one is.

Someone told me it could be the sensor in the TB that detects the position of the throttle. I'm not sure. Any Ideas?

 

P2135 Throttle Position (TP) Sensor 1-2 Correlation ECM, PCM

 

yeah I found that one out earlier...I ended up looking it up on google...lol.

 

yea there's a DTC list on here

 

What can I say i got lazy an didn't want to look for that...so I took the easier route. Just got to figure out what exactly is going on. someone told me it could be an injector...but no one is for sure the proper way to go about fixing this. If it still had a warranty I would just say screw it and take it in but I don't have any warranty on it so I'm SOL.

 

I say switch out the Throttle body.....see what happens...you might have jacked the TPS when you cleaned it....plus....bank one sensor one is the o2 BEFORE the cat....also....just an idea to eleminate it....have your ECU reflashed....I had the 0171 come up after I had my cat replaced...what you use to clean it???....too bad your in bamma.....Id help ya with that.....good luck

 

Throttle Body cleaner. I think we have it figured out tho. Got to replace the front 02 sensor and change the spark plugs. I just have to get that damn cover off. Someone decided to tighten the screws way too tight and now I can't get them off. So I got a challenge infront of me with that. I'm going to start that route and see what happens. here is a video of me driving it today.

flashing cel is bad, shouldn't drive it too much like that man...sounded pretty bad while accelerating in that vid

 

See I don't know that and I have to depend on this car to get around. What does the flashing CEL mean? Running too rich?

 

from what i have saw/read when the cel is flashing and car is sputtering it could be a bad/cloggged cat (could possibly explain the o2 sensor code) but you have other codes too so i'm not sure

 

he is the thing, It only flashes when I'm at like 1/4-1/2 throttle. If I just go normal it just spudders hard as hell and if I get on it there is no problem at all. Plus if you look at the display i was only getting like 14 MPG. Earlier today I was only getting 11. I also just found out that this car has the GM Stage 2 kit on it. So after I get this fixed I need to get it tuned right.

 

The MIL Maitenance Indication Lamp on is the car's way of saying "Ouch that hurts" When it flashes your car is saying "Hey that really hurts!"

 

from listening to the vid...sounds like you have a dead cylinder.....if you have sputtering Im thinking you have a injector out.....and with the O2 lightand the misfire light....its possible....also....when your idleing...what does the boost guage say...it should read betweenabout 16-20 inches of vacum.....if its not...then id say your engine is screwed.....if it is in that range....then id go more towards fuel/ignition/ EVAP systems....

 

yeah the boost gauge is reading normal like it was before. I was going to start with the 02 sensor and plugs first and see if that works. If not then I'll work my way up the ladder. Then I guess the injectors then coils. If I get that far and nothing works I'll just trade the damn thing in on a ss/tc...lol

 

Flashing cel is a misfire indication(a Bad one)
Check your plugs first !

To remove those screws by the best tool ever invented for that
its a impact driver($10 at a tool depot of some name)
you turn it with your hand as you hit it with a hammer,it will get the philp head screws out without wrecking the heads.

 

^ Awsome man! I changed them out today and wouldn't you know she is screaming, no back fire, no spitting or spuddering, and it's just out right fast as hell now. I am posting a pic of one plug that gave it all to get me where I needed to go till I could get this done...lol. Poor thing didn't stand a chance...lmfao. Glad I did this before anything. All the codes are gone now and I'm freaking happy as hell! Thanks to all who tried to help out and come up with a solution. You all are awsome!

 

holy hell...those plugs are f#cked!!!
at least it was a cheap/easy fix

 

yeah. I've never seen a plug like that before. All the rest of them was normal foul/burnt. This was the #2 cylinder plug that looks like it just blew up. But now I can see what it was running like complete crap.
