I have a 2004 Honda Odyssey EX with 6 Cylinders and approx 52000 miles on it. Last Sunday I felt while driving that the car is misfiring and may need spark plugs. The check engine light came on and started blinking, the TCS light came on too. Being Sunday the choices were limited so took my car to Sears Auto who replaced all 6 spark plugs and the O2 sensors based on diagnosis codes and the car seemed to be OK after that.
This week I find a new problem: Every time I start the car and start to drive without idling - around 20 seconds into the drive I lose engine’s capability to pull, the car stays on, the RPM drops to what would be at when it idles and even pressing the gas pedal does not do anything to the RPM. 2-3 seconds later I get full power and the car drives without problem.
If I idle the car for 20-25 seconds before I drive I do not encounter this problem.
If the engine is hot and recently driven I do not encounter this problem but if I leave the engine off for a few minutes I do get the problem.
I almost died last night as I did not idle the Car and tried to turn left and lost power while the oncoming traffic was fast approaching - luckily the car picked up power.
I need your help in guiding towards the problem - what it could be and what am I looking to spend to get the car fixed. There is no check engine light on. Please help.
