how to solve engine idle for your car

When the engine is cold and you take your foot off the gas pedal, the engine runs very rough and may even stall. When you run the engine at higher speeds, it seems to run fine. If your car shows you those symptoms mean that the engine is idling. And there could be a number of problems causing the issue.

1: There may be a serious vacuum leak, clogged fuel injectors, maladjusted ignition timing, a busted cylinder, faulty spark plugs, a damaged distributor cap or other issues. Therefore, it’s important to check and replace vacuum lines as required. However, most of time there’s no visible damage. In that case, you can perform a leak test. To do this, you will need a vacuum gauge. Disconnect the hose from the engine and hook it up to the gauge. Start the engine and let it idle. The correct reading specifications for your vehicle can be found in the owner’s manual. If the readout is too low, then there is either a leak or a blockage in the line.

2: When stalling is more intermittent, the fuel pressure regulator could be out of whack and may be operating at too low a pressure. If it happens, you can check fuel pressure with a fuel pressure gauge and replace fuel pressure regulator. Ps: you better send your car to auto repair because generally it’s not a DIY job.
