Hi All,
Need some help with acceleration issue, here's what I'm experiencing:
This happened when after driving for about 15 minutes (or when the engine is hot) when I step in the gas is not acceleration the engine is jerking like crazy but it I let my foot go and step in gas again the engine is accelerating but keep repeating again.
This only happened when the engine is hot and after 15 minutes.
Sorry for my English.
Thank you all in advance.

 

Is the check engine light on? Any pending trouble codes?Determine if this is an engine problem or a transmission problem.

Possible issues:

Air leaks in the air intake system after the MAF sensor?

Bad ECT sensor, A/F sensor.

Ign coil/wire issues.

 

I am able to hook up a scanner and here are the codes P0171, P0150, P0153

 

P0171 means the fuel system is operating too lean. A possible cause is a failing O2 sensor.P0150 and P0151 point to problems with the Bank 2, Sensor 1, O2 sensor.

Bank 2 is the exhaust system for the cylinder head closest to the radiator. Sensor 1 is the first O2 sensor on the exhaust system when moving from the head and toward the mufflers.

Check wiring to this sensor and if OK replace sensor.

The engine running bad after 15 minutes also points to a bad sensor.

For general interest also check the following:
Exhaust system leaks. Easy to check
Intake air system leaks after the MAF sensor. Easy to check..
MAF sensor. Doubt this is the problem.
ECT Coolant temperature sensor for computer. Check O2 sensor first.
Injector blockage. Doubt this is the problem but can clean.

 

Well yesterday afternoon I start the car and the CEL is disappeared hooked up the ODB scanner and no codes .

 

When the codes disappeared did the acceleration problem also go away?

 

I haven't drive the car yet I will try in the weekend.

 

Sorry I haven't got the time to give everyone an update, here is the situation.

Re-scanned last Sunday no codes, no CEL took car to inspection passed the acceleration problem still occur
I just noticed that every time when the acceleration problem I let go the gas pedal and gently reapply the car acceleration normal and the acceleration problem repeating again when stop and go.
At least is passed inspection give me buying some time to diagnosis.

 

Were the tail pipe emissions checked during the smog test?

Any chance it could be a transmission issue?

 

No smog test I have used the same inspection stations for the last three years for all my vehicles (2017 Odyssey, 2005 RX330, 2008 Accord, 02 Tundra, 97 Camry).

At this point transmission issue is not ruling out I don't want to throw in bunch of money if the repair cost more than the car worth I just want to keep it as long as I can because this is my dad car he parked his car at my house when he passed away.
