Honda Accord

So I just got my first car, a 2008 Honda Accord Ex-l with 55k miles on it from an elderly couple. When I first bought it everything was fine. As I started to drive more and more I started having problems with the transmission.

First off, Its pretty hard to accelerate and when i do i feel the engine working hard to get up to around 2,500/3k rpm, then it gets smoother when it drops down to about 1,500rpm (is this normal?).

Car jerks a little forward

Another thing (my main concern) is that once I’m going anywhere from 30-60 mph and i take my foot off the gas and just let the car glide, as the rpm needle goes down and hits just below the 1k mark the needle jump up to around 1.5k and the car jerks a little forward. (when I’m going around 60-80, it might do this twice). What does this mean? Is that normal?
The last thing might be the same problem but I’m just gonna ask anyways.. Also when I’m breaking from most speeds, once the needle goes below the 1k mark the needle also jumps up (usually between the 500 and the 1k rpm mark).
Whats going on lol?
Ive already changed my break pads and rotors, changed my engine oil (not transmission), and got a fuel injector cleaner. (Not because of this problem, but they needed to be changed anyway.)
Also, whenever i turn my car on I always hear fluid dripping/gurgulling right behind the dashboard. What is causing that?
Thank you very much! Appreciate your service!

 


VSS? Check engine light?

Car jerking forward? Needle bouncing may all be related to what ever is going on. The needle bouncing isn’t much of a concern as long as the engine isn’t dying. The needle is moving around because the IAC (Idle Air Control) is doing its job.

The first place to start would be to have the check engine light codes scanned. Any present codes will assist in directing us toward the problem. This saves time and money. Also keeps us from trying to guess. Most any local auto parts stores will scan the codes for free. Post the codes below in the comments.

I have two codes, one for fuel tank pressure sensor and for oxygen sensor bank one. Ive replaced ftps and both oxygen sensors twice and still get the codes. could there be something else wrong that wont kick these codes out?


First I will need the two codes… post in the comments below.

My 2010 Toyota Hybrid has Diagnostic Trouble Code P3065 and I am not sure what it is. What does this code mean?


There are engine codes and battery codes. The battery they are referring to is the Hybrid battery. This code is related to the battery.

If the temperature indicated by the battery temperature sensor is lower than the standard level (open), or is higher than the standard level (short), the battery smart unit interprets this as a sensor malfunction. If the battery smart unit detects that the HV battery temperature is out of normal range or its value is abnormal, the HV control ECU will illuminate the MIL and set a DTC.

Toyota Code P3065

Hybrid Battery Temperature Sensor Range

Code P3065 Description

The battery temperature sensors are provided at 4 locations on the bottom of the HV battery. The resistance of the thermistor, which is built into each battery temperature sensor, varies in accordance with changes in the HV battery temperature. The lower the battery temperature, the higher the thermistor resistance. Conversely, the higher the temperature. the lower the resistance. The battery smart unit uses the battery temperature sensors to detect the HV battery temperature, and sends the detected values to the hybrid vehicle control ECU. Based on the se results, the hybrid vehicle control ECU controls the blower fan.(The blower fan starts when the HV battery temperature rises above a predetermined level.)

Ford Explorer Sport Trac

Lately my truck has been having problems. When I start it up in the morning, it gives me high rpms, but no movement for a few seconds. This is only made worse by braking. The truck comes to a complete stop and I have to get up to about 3500 rpms to get it moving again.

Also, when I leave work in the afternoon I have problems. When I put it in reverse, without touching the gas pedal it will have about 1000 rpms and roll back easily. The same problem as I mentioned above happens when I put it in drive. High rpms and no movement for the first few seconds of driving.

Any ideas?


No movement

This sounds like you are experiencing transmission related issues. First thing to do would be to check the transmission fluid level.

If the transmission fluid level is low, top it off and test. Check for and fix leaks. If the transmission fluid level is full and has a dark color it may be in need of a rebuild.

All of the sudden started getting a knock noise and it wants to hesitate when you take off. I noticed oil towards back of engine but still have good oil pressure. Its not getting hot and no chips in oil.


The oil leak is probably nothing more than just that, a leak. Anyway you look at a noise it doesn’t look good.

Knock Noise

Lets figure out if the knock noise is internal or external from the engine. The easiest way to achieve this would be to remove the serpentine belt and start the engine. Only allow the engine to run long enough to determine if the knock no longer remains. If the noise is gone, you know the knock is external. You can check the external noise by spinning the pulleys before installing the serpentine belt.

Internal engine knock noise

2000-chevy-blazer-crankshaft-bearings

  • Knocking noise is present at engine idle. Generally disappears as engine rpms increase. This is most commonly a cause of faulty engine main bearings.
  • Knocking noise increases and sometimes gets louder as engine rpms increase. Generally the noise goes away or is faint at engine idle. This is most commonly a cause of faulty engine rod bearings.
  • On rare occasions the balance shaft bearings have been known to make a knock noise.

In either case you are going to end up rebuilding or replacing the engine to cure the issue.

1995 BMW 740i

My BMW has a check engine light on and it runs really rough at an idle. I smell a gaseous odor like it is “loading up” at an idle. What are the possible causes of this?


No reason at all to guess since the check engine light is on. Have the codes scanned and post the codes below in the comments. Just about any local auto parts store will scan you codes for free.

1993 Chevy Truck

The truck idles fine and revs up fine in park. But when I put in in gear, it’s like I push the accelerator and nothing happens. Like it’s not getting fuel. I replaced the fuel filter and the air filter and that did nothing to fix it. Thank you very much.


No Engine Power

The first thing to do would be to check for any stored check engine light codes. And since this vehicle is older than 1995 it can be done without the use of a scan tool.

Once you have the codes you may post them below in the comments for further assistance. There is no reason to guess if you have the codes.

Poor Acceleration

  • Incorrect Ignition Timing – Reset Timing
  • Leaky Valves – Check Compression
  • Weak Fuel Pump – Replace Fuel Pump
  • Dirty Fuel Injectors – Clean/Replace Injectors
  • Excessive Intake Valve Deposits – Clean Intake System
