![]() Depending on the severity of the issue, your engine may even stall, sputter, lack power, or have trouble starting. If your ignition coil is weak or not providing enough power to generate spark, you may notice loud engine noises, misfiring, or a decrease in your gas mileage. Most modern vehicles, on the other hand, will have coil packs or a coil-on-plug design where each spark plug has its own independent coil controlled and timed by the engine computer. In some cases, especially in older vehicles, the engine may have a single ignition coil connected to a distributor that sends the charge to the right spark plug at the right point in the combustion cycle. To my surprise I found a plethora of colors once cleaned up and just asking to be sure so I don't buy a random new fuel pump if i did not need one.The ignition coil or ignition coils on your vehicle provide the power needed for the spark plugs to create spark, ignite the fuel mixture, and start and run the engine. I had to use a brush to remove any dust and debris. Dust and dirt that were so stuck onto the top that rubbing my finger against wasn't enough to remove the dirt. I believe this could be the cause of the fuel pump going out as when I checked the fuel pump area it seems as if it wasn't touched since 2003. If the car is cold again after sitting for a while starts up fine until I drive around for too long. When trying to start the car again instantly stalls out unless I give it gas but if I let go at idle it'll die. Right as I got home taking a U-Turn car stalled out a second time. This time though I stalled out at a light as I was heading home once the idle issues and loss of power started. ![]() ![]() The second day the car only rams for 3 hours and had the same issue after driving around perfectly with no issues in the beginning. I can't thank you enough but I seem to have come across another issue and noticed in the forum you commented on someone's page in 2014 (Committed)Īnyways after idle issues were solved the first day I drove around doing Uber Eats to make some cash and after 7 hours of driving the cars gas pedal starts to lose power, idle issues, almost stalls out. If anyone can help I would appreciate it!Ĭlick to expand.Hey PCB so I've been gone for a while due to waiting for the JIS screwdrivers to come in, they took their time and the car for the last 2 days took it's time but honestly fixed itself relatively fast. The car at that low idle feels like misfires but no CEL, if I give it gas when warmed up it will lose power intermittently. When warm on startup it hits 1000 rpm and drops to 200 rpm goes back up to 1000 then drops to 100 almost stalling the sits at 900 and slowly falls to 500. On cold start up it sits at a low idle of 1500 when it normally used to start at 3000 rpm on cold. Now at this point I am stumped I spent the last 2 days inspecting and cleaning the same parts I just mention and am at a loss for words on what to do. I've personally cleaned the intake manifold, EGR valve, MAF sensor, CAI filter by hand and can say they also improved the idle issues. I've replaced the spark plugs, ignition coil packs, spark plug wires, fuel injectors all around 128000 miles when I had issues with misfires before, fixed the misfires and car ran great for a couple weeks. For information on the car it's a 2000 miles, automatic transmission. Hello I've used this website multiple times when troubleshooting my P5.
