Thanks. The Shaky system has stopped and the RPM is stable now, My Rewire detected that the O2 sensor (Upstream) seems to be Faulty and removed the cables pending I get a new one!

I hope this doesn't have any negative effect on the engine though as I'm planning on getting a new one directly from AliExpress and would have to drive it during the waiting period before I get the sensor

jceesquare:
You most likely have a loose connection for your MAP, and Knock sensors.
Replace socket if brittle and broken. If it doesn't work, replace sensors.

The effects would be.
1. Your car would be running rich and in permanent open loop (read more on this).
2. If you have a direct fan connection, it makes it worse. You'll have more carbon build-up within the engine as a result.
3. You'll spend more on petrol.
4. If you still have a catalyst in the exhaust (which I doubt), you'd run a risk of having it blocked which I believe you don't want that to happen.

If you must buy from AliExpress, don't go cheap or you'd be wasting your time and money.

Good morning gurus,

My 2011 Toyota Corolla jerks on entering gear 2 and afterwards selects perfectly. When I scanned I got code: P2770 as displayed in the image below

My mechanic have disconnected and connected back the Brain box and also have serviced the valve body but the problem still persists.

Please, help on what to do here.

Your best bet is replacement if the torque converter switch/solenoid or complete valve block replacement.

I drive a Camry 08 4plugs

I noticed a wobble on the leg from the front passenger side. This happens mostly when I have accelerated now cruising (coming downhill) without matching on accelerator. So when I want to accelerate again I feel those damn wobble otherwise car accelerate just fine.

I have change the shafts (first I changed the outer ones of both legs) then when it continued I went to change the inner shaft cup too. But I still feel same thing.

I called a second mechanic I trust to drive and feel but he said car is fine and accelerate fine and that he didn’t notice of feel anything.

But when I drive I feel it and it even makes a wobbly sound too.

I have done wheel balancing and alignment too.

Don’t know what else to do. Pls my experience engineers help me. What could be wrong?

You have a misfire, scan and check. It could be a coil, a plug, an injector or bigger problems such as electrical malfunction or cylinder low compression.

Were you there to confirm if it's fake or genuine?
Most of you just sit wherever you are and type whatever you feel like typing without verifying if it's correct or not.

FyI, genuine plugs dey, but na money.

Nissan Pathfinder 07 key showing the security feature (a car with a key inside) especially in the morning during the first start of the day, this is quite frustrating but after the first start it won't happen again, sometimes it takes between 30-1 hour try while some days it starts on the first try. . I have the option of removing battery head still this does not solve the problem..

Please car experts help me solve this issue

Hello Chief,

Please I drive an 07 Accord, it was driving well, no problem at all for long until the Airflow stopped working, I gave it to my Old Mechanic who tried various Airflow meter sensors without anyone working, unknowing to me, the car was using the Brainbox of an older accord before I got it, which made the Airflow not to work again, so I took it to Oyingbo and the worked on it, I got a new brainbox and the car stopped smoking, but while driving home, I suddenly noticed the car starts to jerk once it nears 3000rpm, I could not go back as it was late and I lived far, so I just took the car home. I made a quick research and found out the VTEC solenoid is most times the culprit for that, so I ordered for a Tokunbo and my mechanic installed it for me. On test driving, the car was accelerating fine, it was going past 3000rpm and I thought the problem was solved until it started again a few days later. I just got a scanner and scanned it and it brought up a 'p2646 Rocker Arm Actuator Stuck Off' code, I don't know if you have a clue how I can sort that out, will appreciate your response, thanks.

You nay have to open the vtc and vtc sensor and vtc solenoid and inspect the screen, if it's fine and not leaking, run a live data scan on the intake and exhaust cam to observe the behavior. Your mechanic may have to eventually replace the intake camshaftif it's worn out.
