Rough means misfire,
there are in fact over 50 causes.
hard cold fact.
1: new spark plugs tops list for 100 year running now.
skipping tuneups are you>?
scan it yet, no.
if you scan it , it can tell you which cylinder is misfiring or all of them.
kinda super useful knowing that.
scan it, YOU DO , THEY DO, pick one.

Rough idle is from faulty injectors or maf/vaf sensors or vacuum leaks
run the fault codes to determine the fault area

SOURCE: 988 Wrangler will not idle and runs rough

check vacuum lines would be the first thing i would look at. try taking some carb cleaner and spraying the lines and if you get a change in idle you have a leak

SOURCE: 1999 jeep wrangler no reverse

i would say your reverse gear is locking up on you and that you need to get it to a transmission shop before you break the gear off trying to back it up,,it will mess up the other gears

Please be fast about checking your fuel pump. It is not giving enough fuel pressure.

SOURCE: replace 1995 jeep wrangler catalytic converter

If it has flanges on both ends, just unbolt it and replace. If it has welded pipes you will need to cut it off and use adapter sleeves and clamps. Really not rocket science...at worst, you may need to remove the hangars on the rear portion of the system to get enough room to install.

Engine will not accelerate past 1200 rpms when in drive and idle is rough in park


Check engine light on? Have it scanned and if it is a p0420 code, that will a catalytic converter code. That will make it run rough and not run well. Usually the catalytic converter will be stopped up. If no engine light on, unclear of what it could be but I hope you get the issue resolved. Thanks and Jesus loves you John 3:16-17 (KJV)

Engine running rich


Sounds like a dead coil pack and needs replaced cause you're getting no fire to those plugs and causing a rough idle. Another thing is, that catalytic converter will only turn red because it's plugged up and needs replaced. Have that checked out friend.

Rough idle


What about the coil packs? Do you have a check engine light on? If so take it to an auto parts store and see if they will scan your vehicle for the codes.

Honda accord ex 2001 check engine light suddenly came on, car started to idle roughly


If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring.
If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.

Start car, runs good, drive for a mile and instant loss of power, power fluxuation, rough idle, accelerate out of it at idle, idle good then when you accelerate or try to put in drive it dies


Have the codes checked and post them to better give me an idea it may sound like it could be a clogged up catalytic converter but checked the codes if it coincides with what i just told you then it is the catalytic converter let me know something thanks.

My Pathfinder runs fine until it gets to about 30 MPH, then the engines starts running rough. The computer code says the problem is the catalytic converter. The car has about 76k miles. That seems to few...


not necessarily, i have saw cadalatic converters on vehicles with 30k on them be pluged up so tight the vehicle would barely idle... i was going to guess that was your problem before i read what the computer said..

I have a 96 Honda Civic HX. When I am at idle the car starts to shake and the rpms fall almost to zero. I took the car to a mechanic and was told that I need a new Catalytic Converter and the EGR ports...


Yes and No. The EGR can cause the car to idle rough and or stall. I am assumeing the check engine light was on and set code for EGR and Catalytic Converter. If the engine isn't running right it is possible the cat won't work right due to improper air fuel ratio that the EGR is causing. To do repair proper the EGR should be fixed then clear codes and see if the code for Catalytic Converter. There are other reasons that would your car to idle rough or stall I am just assuming that this mechanic got codes or tested the EGR right.

1989 Mercury Sable GS 3.0L runs rough and idles down and stalls


Sounds like you might have a stuck open EGR valve. Is the check engine light on. I would replace the fuel filter if it hasn't been replaced, also check the air filter.

Rough idle after timing belt change what can it be?


if over 80,000 miles it could be exhaust system or catalytic converter. If it has been idling rough since you got the belt changed, I would contact the mechanic and just ask. Are the rpm's moving up and down or at all?
