To be honest, that hissing sound might not be from the any lines but it might actually be coming from the evaporator coil. IF that’s the case, that is a 400 dollar fix bud. But it’s highly unlikely that the leak would be caused by excess pressure buildup in the line due to the fan because it’s brand new and would actually create LESS pressure. Therefore, one of the mechanics might have damaged the freon lines and that would be causing you to bring the car back for more inspection…which is poor mechanics in my book.
I’d try driving it around the block, no more than a mile or so and try getting on the throttle a little bit. That might reset the computer and fix the problem. If not tell me, plus how many mile are on the thing?
Because it’s the closest thing I had to an actual picture of the car. I’ll take one today and put it on the post. How bout that 😀
It also might be the transmission, in that case…Hesitation doesn’t always come from the engine. Electronically controlled automatic transmissions are subject to the same kinds of sensor and actuator problems engines are, and have a lot of complex hardware to control. Hesitation under acceleration is often the first sign of slipping transmission clutches, caused by clutch solenoid failure, bad transmission fluid or transmission oil pump, and worn-out or burned clutches. If your vehicle only seems to hesitate in top gear, or over about 45 mph, you may have a problem with the lock-up clutches in the torque converter. Of course, low transmission fluid can also cause hesitation, both because of fluid pressure fluctuations in the transmission, and because of an empty torque converter churning up air instead of transferring power. Modern vehicles will typically self-diagnose the transmission just like the engine, but these manufacturer codes may not be readable with a generic scanner.
Engine hesitation, almost by definition, usually goes back to a misfire in one or more of the cylinders. When one or more cylinders stops firing, the power cuts, and the vehicle hesitates under acceleration. The misfire is causing the hesitation; you just need to find out what’s causing the misfire. Often, it will come back to a “lean” condition,” meaning that there’s either not enough fuel or too much air going in. Clogged fuel filters, failing fuel pumps or regulators, and dirty or malfunctioning fuel injectors are the most common causes of a failure of fuel delivery. The accompanying “lean misfire” will trigger a check-engine light. On the other side, you could have a massive air leak from a bad vacuum line or intake manifold gasket. Failed intake sensors — throttle position, mass airflow, intake air temperature and manifold absolute pressure sensors included — will often cause the computer to think there’s less air going in than there really is. So, as far as its concerned, there’s a massive vacuum leak present.
I thank you for your concern for the financial advice on the car but being the person I am, I see that if I’m going to own my cars, I’m going to put my personal touches on my car. Plus, there’s the fact that I’m financially set for college and stuff like that and with the money left over, I want to put it in my car. As a true car lover, I believe that I will never let go of my first car and if I could have my way, I probably wouldn’t buy another one until i start a family. With the fact that I’m not going to sell the car, the resale on the car is irrelevant. Plus, I have all the tools and supplies I need for underbody rust prevention at my disposal as my uncle owns his own body shop and has told e he would gladly lend me anything body-wise if I asked. I was just wondering what would look the most practical on the car. I’m also doing turbos and engine mods also which I was wondering if you could help me out on also. 😀
