Car stalls when stopped quickly


Car stalls when stopped quickly

Symptom: Car stalls when stopped quickly. You are driving along and everything is just fine … until you let off the gas pedal and apply the brakes. The engine starts shaking and may even stall. Not a good thing to happen because you lose power steering when the engine dies.

Possible causes:

1. There may be a serious vacuum leak.

The Fix: Check and replace vacuum lines as required.

2. There may be a fault in the computerized engine control system.

The Fix: Check engine control systems with a scan tool. Test circuits and repair or replace components as required. (Generally not a DIY job)

3. Broken linkage.

The Fix: Repair or replace as required.

Do You Need a Compression Test?


Do You Need a Compression Test?

Your car’s engine compression can tell you a lot about the overall health of the engine. If your car is blowing blue smoke out of the tailpipe, or if your car is losing lots of oil, you could have a bad piston ring. This will also cause low compression in that cylinder, and a compression test will tell you. The same goes for a bad valve. Even if you are just noticing a general lack of power, a compression test can help you rule out some of the more serious possible causes.

“Thank you so much for all that Ellesmere Port Engine Centre did for me. When I came in for my brake job, I had no ideal that I had been risking the life of not only myself, but of my son also. I am so grateful for all the hard work, effort, and caring that went into fixing my truck for me, as well as for all the care and understanding I got from everyone that pulled together to get the job done in time for me to make it back to work. I don’t think I can every repay you for all you have done. You guys really went the extra mile, and have proven to me that there ARE good people out there. Now I tell anyone that will listen how wonderful Ellesmere Port Engine Centre are. Thank you, thank you, thank you!
