Issue / Question:
For the past 2-3 months, my car seems to be bucking when I try to quickly accelerate from 1st gear to 2nd gear, and from 2nd gear to 3rd gear. A trip from Lake Wales to Deltona normally took 1 1/2-2 hours, and now it takes over 4 hours in a hard rain. I originally thought that this may be caused by the water from the roadway, but for the past week, the same thing has been happening when it’s been sitting for a while and I try to accelerate quickly. I put a version of STP and mid-level octance and tried driving quickly on I-4, but the problem continues. I’ve checked the transmission fluid level and it seems to be okay. My daughter has suggested a transmission fluid exchange, and someone else suggested changing the O2 sensor. I’ve had this car for just over two years and the check engine light has been on for practically the entire time. Would a transmission fluid exchange be the right thing? And how much should it normally cost? Thank you!

This sounds like an engine tune problem. Either it has plug wires breaking down, or it could be a plugged fuel filter. What we can do is scan the computer system to find out why the check engine light is on and correct that problem first. Then, we can check the ignition system and see if the engine is due for a major tune up, and next perform a fuel pressure and volume test to see if it is low or has low volume.
