Hey i was hoping someone could help me figure out a slight performance issue. So i noticed some days my 2013 v6 automatic Camaro has a good amount of power while acellerating. When i give it some gas it goes up in RPM easily or downshifts quickly. But some days i hit the gas expecting the same thing but it requires me to step on the gas even further than usual to get the same power. Its like it wants to stay in the gear its in until you give it more gas. The car runs near perfect and the problem is subtle. In fact i often forget im not getting the right power until im driving and feel that burst of power from nowhere. It seems like if i rev the car to 4k or 5k, after that it drives much faster on subsequent acceleration. Its like it just wakes up. My initial thoughts are that something may be getting clogged until i give it a good rev and lossen up the fuel flow or airflow. I have a washable K&N filter and i try to keep it clean. Not sure if maybe this is the fuel filter getting clogged? Fuel pump issue? Maybe an airflow problem? I have experienced this issue on and off for a few years. Any help is appreciated!
Hey there, I own a 2014 Ford Mustang V6 automatic and she's given me a little trouble the past couple of days. If you'd like to skip to the questions it's in parenthesis at the end. So to update you on its history my car was making a deeper exhaust sound than normal. There was a also a slight bit of power loss but almost unnoticeable. Doing a little research I nailed it down to my catalytic converter. The code I got was a P0420. Before replacing it and spending a few hundred bucks on 2 new catys I attempted to clean them out by using a method I saw by Scotty Kilmer on YouTube. He suggested pouring a gallon of lacquer thinner down the gas tank on a half full tank, and so I did. I followed his instructions but noticed no difference and it was still making the deep irregular puffing exhaust sound. 2 days after poured the lacquer thinner my baby was choking. I had 4 error codes come up P0300, P0301, P0302, and P0303. I had extreme power loss, acceleration delay was insane, couldn't pass certain rpms even on full throttle on certain gears almost all of them, there was a clanking sound at high rpm's around 5,000, I could feel the misfires. I took it to a mechanic and he recommended going to a muffler shop and removing or replacing the catalytic converters. So I followed his advice, I got it removed and replaced but just with a pipe. It solved almost every problem. (The car works beautifully now accept on the 5th and 6th gear even on full throttle the car cannot pass 2,000 - 2,500 rpms and the fastest she goes is 90mph which is not normal. I just cleared the old codes so I don't know if one will pop up eventually but I have 2 questions. Is it safe to keep driving my car in this condition usually the fastest I go on highways is 70 - 80 mph. Secondly I want to know where the issue could be.) Thank you all.
Hello everyone. I have a 1994 Chevy S10 pickup and for some time now I have had a lot of multiple problems with my S10. About 2-3 months ago I replaced the transmission in my pickup and ever since then my truck has been acting strange. I will list some of the symptoms. 1: Vehicle has trouble accelerating and RPM's aren't stable. 2: Idols very rough when sitting at a stop light or sitting in park. 3: When accelerating, vehicle will sometimes back fire under pressure and make a spitting sound on the drivers side. I have done a lot of repairs on the vehicle. I have replaced the O2 sensor near the catolic converter, replaced old intake manifold gaskets, replaced exhaust pipe donuts and have also welded and repaired all hole damage to tail pipe. There are NO exhaust leaks that I can smell, see, or feel. I also replaced a digital part on top of the engine on the passenger side next to the valve cover, I think it had something to do with the vacuum lines and I replaced it but I do not remember the name of the part. I even reset the vehicles computer after replacing these parts. I replaced the hole spark plug system and all vacuum lines have been replaced as well. But the vehicle still runs bad. Any help is much appreciated. Thank You Kevin
