Kia - Optima :: 2004 - Small Jerk After Driving For 20 Minutes / Engine Light Comes And Go
Nov 1, 2015
04 Kia Optima (116,000miles) will drive ok for 20 min. or so (last time 10 miles) I'll hit a bump, stop, turn a corner, or drive on hills (basically any condition) and it suddenly acts up after a small jerk (engine light comes and goes and I cannot get anyone to read codes correctly). I have to drive with my foot on the gas at stops if it gets really bad and it wont come down from above 40mph unless I break and feels like it wants to stall when trying to accelerate again after stops and difficult to sometimes get past 30/40mph, Once shut off, It has trouble starting, but will start.
I have had the PO335Crank shaft position sensor replaced three times, (last time by dealer) New battery, new spark plugs, the throttle body was cleaned, and high octane gas cleaner in the tank as well. Every time I take it in (6 or 7 times, different places), they say "it's not acting up right now so we don't know" .... I am curious about broken flexpipe..

I have a 2000 VW Passat 1.8T and when I am driving and hit the gas all the way its like the car does a small jerk and then proceeds to go. Nothing too hard but def. noticeable. I just installed a boost gauge (autometer) and I am running a nuespeed chip. The PSI is maxed out @ 6-7psi. I also changed the mass air flow sensor car ran fine and now these problems started happening.

I have a 2012 GLS automatic with 78,000 miles on it. Till now I never had any issues but recently I started having issues with starting the car. Its taking few tried to get it started. This happened 3 times and I got it checked at 2 places and they said everything (battery, starter, alternator) looks OK and they may not be able to find the issue until car breaks down as issue looks intermittent.
Later one time, I was driving on local road and car kept moving but I felt a small jerk like engine is stopping or gear shifting...and RPM fell to 0 but car kept moving. I stopped on the shoulder and turned off the ignition. After few trials, car started again and moved fine. This same issue happened today morning on the fwy when I am driving at 70 mph. It started after few trials.

I have a 1992 Chevy S10 with 84,000K on it. It drives fine but when I get on the interstate and am driving 65mph for about 5-10 minutes the 'service engine soon' light comes on sometimes it takes longer. It only does it when I'm driving on the interstate and not if I'm just driving around town. It also doesnt turn on all the time but when it does come on it stays on until I turn the engine off.

Fourth attempted fix failed. 2 times with "regular" mechanics, once with Kia dealership. My 2006 Kia Optima will drive fine for about 20-30 minutes (last time 18 miles) I'll hit a bump, stop, or turn a corner and then it acts up (engine light comes and goes). I have to drive with my foot on the gas at stops it wont come down from 40mph unless I break, It once wouldn't go past 40 though and I thought it was going to stall out on me. Once shut off, It has trouble starting, but will start.
Shut it off, it runs again fine for the next 10min or more. I have had the crank-shaft sensor replaced three times, (last by dealer for double the cost) New battery just put in a couple of months ago, spark plugs, the throttle body was cleaned, and threw in some high octane gas cleaner in the tank as well.Every time I take it in, they say "it's not acting up right now so we don't know" ....The only other issues that don't seem too important right now are back sway bar and flex pipe.

The past couple of months my ABS light has been coming on randomly. It comes on after several minutes (or hours sometimes) of driving then stays on. I wrote it off as a bad sensor but now, even when under light braking, if I hit even a small bump in the road, I can feel the ABS activating in the pedal. Seems like more than a sensor to me. I know I have a front wheel bearing going out but how would that be related? 2007 F150 5.4 2wd

I've been having some trouble with engine hesitation after driving for 15-20 minutes and poor MPG on my 2004 Hyundai Santa Fe 2.7L. I've been slowly running through some tests as I learn how to diagnose car troubles. I just ran a voltage test on my 4 O2 sensors using a bluetooth scan tool and the Torque Pro app. I ran the tests at idle after warming up the engine. To me, the upstream sensors seem fine but downstream sensors are not behaving like they should. Aren't the downstream sensors supposed to be relatively flat around .45 volts while the upstream sensors fluctuate steadily between .1 and .9?

My wife's car is throwing at p0306 code. I have changed the park plugs and the check engine lights comes on after 5-10 minute of driving and gives the same code. Can I move the spark plug wire to another ignition coil bank to test the coil? The picture shows the current plug locations on the ignition pack. Is there any certain order they need to be in or can I just swap 6 and 5 since they are the closest together?

@75000 miles my first check engine light. Here are my symptoms......
~After i shut the car off the fan keeps on blowing at a very high rate as if the car is over heating, its currently 45-50 degrees.
~On cold morning when i start the car up and turn the steering wheel I hear a very loud whining sound, but after driving for about 20 min and the car has warmed up the sound goes away.

Yellow brake light turned on while driving in rain, then for some reason turned off. I had read somewhere this may be an indicator of wear on brake pads. I have a 90 mi. commute round trip, I will check again if this turns on and stays on. For now, it is off. what could be causing this?

My 2005 STX 4.6 fuel pump crashed a couple of months ago. A couple of days after having it replaced I started having hard/rough starting problems accompanied by a 0300 and 0301 code. I reset the codes several times and they only come back during the 3rd or 4th hard start, never while driving. The hard starts occur after the engine is shut off for more than a few minutes after driving. I have replaced the plugs, #1 COP, remaining COP boots, Cam Pos Sensor, Fuel pump drive module and had and FI. Also had the fuel pump replaced again on warranty thinking maybe a bad check valve. Again...it worked perfectly for a day and now I'm back to square one. Haven't gotten any codes YET but its only been a day. Bad injector? EGR?

Over the last few months I've noticed that there was a small 'Jerk' from the car when pulling away at low revs. It seemed to happen around 1200 RPM/20 MPH put only when pulling away very gently. It has been getting worse in the past two weeks. The car needs a service and I was going to get the fault looked at when in for service. Last night the 'ESP OFF' and the 4WD fault indicator came on (4WD lamp flashing). Since the fault lamps have illuminated, the car has stopped 'Jerking'.

I notice that when I jerk the steering wheel left and right fast (1-2 inches) I hear small knocking sound. Seems to have narrowed it down to the right side steering rack inside the booth.

2004 BMW 325i automatic - 127,000 well maintained miles - never abused - at 35-40 mph in high gear the rpms will periodically drop 200 and there is a noise like driving over small rumble strips after which the rpms instantly return - the speed does not vary. the dealer installed a warn drive shaft bearing but the problem continues - it is a bit less noticeable in sport mode - what can it be? computer - transmission - ????
The intention is to keep it for many years so if it is a transmission problem would rebuilding the current one or putting in a new one be the more advisable solution?

It has 85K miles and rides very choppy/harsh. I feel even a very small dip/hump/bump when driving and it's coming from rear of the car.
What needs to be replaced and/or checked other than the rear shocks? Everything is stock and correct tire pressure.

My tpms light came on tonight after 15 minutes of freeway driving. I checked the pressure in all 4 tires, and they were all right about 36 lbs. The door jamb tire info says 33 lbs cold, so this seems about right to me. why the tpms light might have come on? Is the spare tire hooked up to the tpms system? My Passat is only 1 month old, so I'm surprised the light came on.

We got a 1990 celica gt with the 5sfe in it. first night driving it after about 30 minutes the oil light would flicker at idle. We checked the oil, it was nasty so we did a complete oil change. Didn't fix the issue. Well then we developed an oil leak at the oil pump seal so we replaced all those. We had heard the sending units were notorious for going bad so we took it out and put an aftermarket gage in it. Still an issue.
Ok so then we checked the main bearings to make sure they were ok, they are fine. Normal wear. No clogged oil screen either. We then was told to try a little bit thicker oil so we did that. Still the issue. Here's what happens. start it up cold at idle is about 50-60psi. Let it warm completely up and it drops to 18-20psi. When you rev it up it rises.
Ok well after driving it for about 30 minutes after warm when I came to a stop it dropped to 0! Rev it up and it rises a lot. Held it at 2k rpms and it stays at about 30-35 psi. Ok as I'm driving it, it has good oil pressure. Motor is not making any noises other than the common Toyota valve chatter.
We have ran cleaner thru the engine thinking so gunked up ports and still no change. We are at a loss. Like I said cold it's fine, revving it up after being hot is fine. Driving it is fine. but boy when the engine is hot n u come to a stop or at idle it's nothing.

2004 Kia Optima has the AC compressor locked up. What else needs replaced on this car to properly do the job? I can pull a vacuum, and add refrigerant, but is there a dryer that needs replaced? What needs flushed?

Sonata NF 2.0 ... 3 days ago, my care drove for - 4 minutes then engine shut down. Try to re-start the car but unavailable. I towed the car to workshop, they claimed high possibility is the fuel pump faulty.
Initially a check was done found fuel pump good (the technician disconnect the tube before the fuel injector assembly). They did a diagnose test found no error code registered.
Subsequently check on the fuel pump found no fuel come out before the fuel injector assembly (same as previous, disconnected before the assembly). Fuel pump was replaced. The engine can start running but will shut down after a while.
What is the possible cause and how to identify the root cause.

I have a 2004 F150 4x4 5.4. Over the last few weeks I've noticed that when the truck has been parked for even a short time, when I start to move out I am getting a thumping noise from the rear, almost sounds and feels as though I am driving over small speed bumps, but once i get going it seems fine. Where to start?
