automatic 1zz 05 base vibe hopping when accelerating

[NoRemorse249]

OK so I put a cold air intake on it. Ran it around my batt down under my headlight n behind the left side of my bumper. With the stock air box it ran fine. I never noticed a hop or slip or bog with stock intake. When I put the cai on it bogs if I jump on it hard from a stop but after it gets Rollin its OK. Till 2nd gear I will go then back down and go again it does it like 3 times thru second gear. When it goes to third (still on the floor) it loses a lot of power and hops some more. With it on the floor it absolutely will not hit fourth. It taps out at about 92mph if I back off to 75% throttle it goes to 4th but doesn't go past 97mph. With the stock intake I could at least hit 105mph in 4th after running for a while at full throttle. What is wrong with this thing? I will post any pictures u ask for I really want to fix this issue.

Any Codes (Check Engine Light)? Have you replaced the PCM yet? It was under a recall. Sounds like an issue with PCM or maybe the MAF or a plugged air filter. I've put an SRI on a 05 TRIX w/AT and 03 Vibe GT with no issues. Have you put a code reader on it yet?

[NoRemorse249]

Put one on it yesterday at auto zone. The guy said it was my torque converter and my bank 1 o2 sensor making my check engine light come on. I just got this thing January of 2013. I'm not sure I'd they had the pcm recall done or not. How could I find out? When I first put it on I thought maybe I needed to upgradey fuel injectors to keep up with the higher air capacity coming thru the intake so I ran some cleaner thru em and it kinda fixed it but its back a few days later. When I'm in 3rd and throw it to the floor now it doesn't go anywhere just gets all sporadic and sticks about 3000 rpm and they jump back n forth between 3000 n 3200rpm like crazy. But doesn't accelerate. Ima change my o2 and torque converter. See what happens then.

[Salsa Guy]

Don't change anything!!!! Post the Code numbers first! The O2 sensor isn't likely bad but it telling that something else is wrong.The torque convertor maybe related to the PCM or a bad/damaged wire or connections

[NoRemorse249]

he gave me no codes just told me it was the torque converter and bank 1 o2 sensor ill go back and get the codes and post them tomorrow on my way home.

[Salsa Guy]

I'd suggest buying a code reader. They are cheap and very helpful.

So putting a CAI on causes immediate problems and you're going to change the torque converter??
That makes absolutely no sense.
Put the stock intake back on and hopefully the problem will go away.
Here's my contrary opinion:
The stock intake is just fine. It's not restrictive and the stock filter is more efficient than those little cone filters.
I've verified this by using a scan tool and measuring the MAF with the filter removed and the filter box open vs everything in place.
All the CAI or SRI does is make more noise.
What I did on my car is route the snorkel from behind the battery to behind the lower grill, where the air is cooler.
I've measured the intake air temp with a scan tool to verify.

Interesting observation.

[NoRemorse249]

i had the stock on it and it still hops when im on it hard. no matter what the torque converter puts out P0741 and the 1st bank 02 sensor puts out P0171. so regardless i will be changing the 02 sensor and the torque converter. that is if i can find a torque converter. its damn near impossible ive looked all over and cant find one for the 05 fwd base 4spd. everyone says ill have to go to the dealer. that would be the most expensive way to get it (i believe).

[Salsa Guy]

DON'T REPLACE THE O2! You have an air leak somewhere. Your engine is running lean which is very bad. Don't be hammering the gas until it's fixed. Use some carb cleaner and find the leak.

Here's info on the P0741

- Low transmission fluid level, check the fluid
- Dirty transmission fluid, replace the fluid and filter
- Faulty torque converter clutch solenoid valve, check connections/wires
- Torque converter clutch solenoid valve harness or connectors, check connections/wires
- Torque converter clutch solenoid valve circuit is open or shorted, check connections/wires
- Transmission internal mechanical problem, SOL Tranny work $2K

how will i know the leak when i see it? ive taken alot off the front of my car and got in there and cleaned it up pretty good with throttlebody cleaner and i cant find any leak. i sealed the ends of my intake and put an air compressor on it and felt all the seams and i didnt feel one.

[circuitsmith]

how will i know the leak when i see it?

With the engine idling spray some carb cleaner, starting ether, or an unlit propane torch around the intake manifold and other vacuum lines.
When you get near the leak the idle will change, because it will be sucking in flammable fumes instead of air.

wow that is awesome didnt know i could do that. ill do it tomorrow as its raining cats n dogs today.

[NoRemorse249]

been raining alot so due to the fact that i have no cover still havent got out and found the leak if there is one. but noticed that after driving for a while if i make a short stop for like 20 mins it has a hard time starting again. i have to just let it turn over and over and it will start kicking really rough then it will start up. could someone explain that?

Sounds like it has no fuel pressure when you do a cold start and low fuel pressure when running, which could make it run lean. Check all your vacuum lines and make sure there are no leaks (the carb cleaner). For you, forget the trouble codes for now as those are only symptom's - not the problem. Just as a blown fuse is not the cause of a problem but only a symptom of something else that is the cause of the problem; so to are the trouble codes. You need to start trouble shooting to find the problem. Check for vacuum leaks, and check your fuel pressure and fuel volume. Your symptom's so far could be caused by a bad fuel pump, fuel pressure regulator, fuel line check valve, bad vacuum leak, plugged fuel filter, etc....it is running lean and you could damage the engine if you keep running it. Sounds like it is getting worse the more you play with it.

Try this when starting the engine; turn the key on for 5 seconds, then turn off, turn back on for 5 seconds, then turn back off, turn key on for 5 seconds and then try starting the engine. See if it starts up. Do you know that is happening by doing the above? Doing a fuel pressure test can tell you a whole lot more. Unless you are building a race car, put the stock engine parts back on. The motor is made and designed to run with the stock parts it comes with. Once you change one thing that makes any real difference to performance, you are going to cause a new problem as now the system (engine) is not in balance. In this case, as it is looking would be the air/fuel ratio is not balanced. The problem could be something all together different but with only the information you are supplying, it is still anybody's guess. Guessing is not cheap so you need to test.

i got into it and started playing around with my cai and i fixed the issue not sure how but it starts fine and runs like a bat out of hell so im good. it feels like the cai gave it a lil more accel not much but still better than it was. havent checked my ts yet. ill do that on interstate tonight when its clear. and yes since this is my first car ill have it forever. i have many ideas for it. it will be a race car when im like 35 im 22 now.
