Why is my 97 ford f150 shaking after sitting idle for a while? - 1
Added (1). it begins to shake after being on the road for about 30 minutes or so. Seems to happen after the engine gets good and warm but it only happens when i'm idle. It shakes and stutters like its fighting to stay on
figured this may be an air leak somewhere. What else could this possibly be?
One of the cylinders is misfiring. Could be a bad spark plug, or wire.
It could be a vacuum leak, or a bad IAC motor, or a bad spark plug, or wire, or coil, or valve, or head gasket, or worn rings, or fuel filter, or fuel pressure, or worn engine mounts, or…
Since you've already "figured" an air leak, check that out, then start in on the list.
Get a tune up. Replace the fuel filter. Check fuel pressure. Get a scan tool and check for any codes.
- Why is my engine shaking during idle at stops and park? I got a ford 1999 taurus SE with 100,000 miles on it. I just changed the spark plugs and wireset out and it got even worse. I was thinking the IAC might of just gone bad but before I go get one I wanted to ask if there was anything else I could test before buying more new stuff for it.
- Ford Ranger 4.0, 172,000 miles rough idle when starting after sitting overnight or after 2-3 hours. Starts 1st crank, idles rough 1 minute? Or so and then smooths out and runs fine. New heads and gaskets. Cleaned MAF sensor, throttle body and air intake sensor, new IAC valve, new air and fuel filters, new PCV valve. No smoke coming from exhaust and No check engine light. Any ideas what's causing this rough idle?
- I bought an Actron CP9125 Code Reader to try and diagnose a rough idle at cold start on a 98 Ford 4.0 engine. The rough idle had not caused? The CEL to come on. I plugged the code reader in with just the key on and pressed read and the little asterisk goes half-way across the screen one time and stops. I press the read button again and it reads 0 codes. I was thinking it would scan multiple times to check for pending codes or other issues. I tried it with the engine running and the same thing happens. Is this code reader operating properly?
- Why is my car shaking when idle? Here's the back story. Car is a 2001 Ford Focus hatchback. Check engine light recently went on for a EGR censor. As of yesterday my cruise control will not work, and when I went to turn my car on today it is making a chugging noise and vibrating. When you gas, it stops vibrating however as you slow down it starts again. What are possible things wrong with the car? (And yes, it has plenty of gas just filled up two days ago.)
