I have a 2005 Exploer Sport Trac with 236K on it
recently changed all plugs & wires as well as the coil pack to stop a sputter in the motor. it worked. now, very periodically and only for a split second i will loose all rpm and then back up again to normal. I was told that the computer may be going but i've plugged it in and it wont turn on a reader. other than that one hickup she runs like a dream now.
Periodically the engine light comes on and then when I hit the gas it "stutters" and the car jerks - similar jerking feeling when you are learning to drive a stick shift but this car is an automatic. I have to take foot off gas pedal and keep slowly applying again to building up speed. The stuttering stops as soon as I take my foot off the gas pedal. Sometimes when I stop the car, turn it off, the light will turn off and the car drives great. Sometimes that doesn't work and the light stays on for a day or two then magically is gone when I start the car again. I have noticed the light comes on most often if I haven't warmed it up enough before driving, but other times it just comes on. I have taken it to two different Honda dealers and they don't know what the issue is.
View 3 RepliesMy Service Engine Soon light came on in my 2005 explorer. I took it to Advance Auto Parts & they plugged it up to the reader and it said something about "coolant." The guy who did it could not tell me anymore, other than I needed to take it to a shop. What this could mean?
View 5 RepliesI have a 99 Lumina 3.1l. I live in a cold climate (-15f). I hadn't driven the car in 2 months, and the block heater doesn't work as there is a short somewhere.
I want to get the car on the road again and before insuring it I tried to start it Friday. To its credit it started up almost right away - its always been great in the cold. I let it run for 30 minutes to heat everything up.
I insured it Saturday and went to start it and won't go. Turned over & over & over, and the engine will chug every now and then but won't catch. Its a few degrees colder than it was Friday, but not by much.
It did have just under a quarter tank of gas, so I'm wondering if it could be condensation in the fuel system somewhere that was sucked in while idling on Friday? If so I don't really know what to do about that. Or could there are other things to check/try.
I'm replacing the plug on the block heater, but don't think thats the short. I was going to drive it to the garage to have them replace the cord (as I doubt its the block heater itself) but have to get it started to do that
About a week ago I purchased a new K&N air filter for my '09 GLI (6spd stick & all factory options with 55,000k on the odometer). Outwardly the vehicle seemed to run better (although a new clean air filter of any type will make a vehicle run better) however, 2 days later I noticed that the engine seems to chug a little when it was cold. Not missing like a plug wire off but a chug where it surges forward then holds back continually until the engine warms up. This persists today. I've also noticed a little bit of a rough idle. I've re-inspected my installation and nothing seems to have come loose and the filter fits perfectly.

View 4 RepliesI have a Mazda 626 (V6) with about 150K miles and a funny engine racing problem. It occurs only when I'm going highway speeds (for me, 70MPH) and the car has been running for about 15 minutes. The engine will race, then chug and RPMs will drop down again, then it will race, etc. If I slow down, it will stop racing, but often start again as soon as I put my foot back on the gas pedal. If I don't get on the highway (running 60MPH and under), the car is completely fine.
I've taken it to my mechanic twice; the first time had the fuel filter replaced, the second time got new spark plugs, but it's still doing it. What else it might be?
I have a 05 dodge Ram that periodically wont start after I stop at a store etc. It happens about once a month and will start up after sitting for 1-8 hours.Ive had it to the dealer , diesel mechanics, etc. with no luck,( Cant reenact the problem and nothing shows on the computer).
View 7 RepliesIn the last couple of weeks I've been getting a whistle or whining noise I think from under my car periodically. It doesn't happen when I start the car, not when idling and starts at about 20/30 mph. I've had the car in the shop for regular maintenance, just replaced front bushings, put on new rear brake pads and new rotors. I've checked the car for anything that might cause wind since it comes and goes even while driving. Seems worse in hot, damp weather. Back to the dealer today because it was loud and they say drive shaft, but there is no vibration and the car is running very smoothly. It's driving me crazy when it happens because it almost sounds like a plane landing.
View 13 RepliesI have a 2013 Avalon Hybrid and am having trouble while using the cruise control. The "sensor needs cleaning" goes off although the sensor has been cleaned several times. Also, the sensor sometimes doesn't register a vehicle in front of me. The Avalon has been looked over by the dealer (several times), the sensor was replaced but the problem persists. Because it works periodically, it's difficult to diagnose a problem. Also, the PCS warning goes off periodically. Not sure if that's a related problem. It has gone off while driving through an intersection with traffic sensors (not consistently).
View 5 Replies1995 2.3L has boggy performance. Engine shakes. Exhaust smells of gas. Barely moves. Pulled spark plugs two of them were blackened other two clean. Replaced fuel filter. Changed ICM. Noted small hairline crack on coil pack housing. Still have boggy performance. No CEL light on. No gas coming out of vacuum line from rail regulator. Engine will thump periodically when accelerated.
View 13 RepliesI own a 2010 AWD Santa Fe. It gets factory scheduled maintenance at the dealership. Since owning ( i bought it used from Dealer, it was driven by dealer) it has periodically revved while driving. Often at lower speeds while accelerating from a stop. The engine will rev and the car will act as if it is in neutral. Then, after a few seconds there will be a sharp jerk as the transmission(?) engages and the car lurches forward. My dealer told me it is normal. This does not seem normal.
View 1 RepliesMy 2001 Saab 95's engine periodically downshifts. Usually the downshift happens after some highway acceleration. The ABS light turns on at the same time as the downshift. The road conditions are always dry. The downshifting started last summer and has continued during the winter months. The alternator was recently replaced but the downshifting periodically continues. MY Saab repair shop cannot figure out what the issue is.
View 4 RepliesI have a 2003 Camry 4 cylinder with an exaust leak. On first morning start after the rpm drop to 500 the engine will shake periodically until I drive about half a mile then all is fine. I cleaned the trottle body at the area of the flap with throttle body cleaner and a tooth brush, and gave the car a tuneup. The problem went away for about 4 days but is back. What can I do to fix this.
View 2 RepliesI have an '07 Sonata and I just recently had an after market HID kit installed. My car has since periodically stalled and the check engine light came on. I ran the codes and they are P0698- Sensor C Reference Voltage CKT low, and P2110- Throttle Actuator Control System forced limited RPM. What does this mean and how can I fix it? I had a second battery installed so I know I have enough to power everything.
View 8 Repliesi have a 2007 F150 Fx4, with 94,000 miles. When I hit the speed of around 40-45 and I step on the gas it starts to chug until I press harder down the it gets out and runs just fine. The thing that confuses me is it doesn't always do it. Id say about 3 times a week. I am replacing my fuel filter tomorrow. I purchased this truck with 85k on it, and this just started happening. The spark plugs have never been changed. And am thinking about taking it in to get those done too. I also tested all my injectors and they are all working. No codes have been thrown either.
View 6 Repliesso i was driving along & my 2000 f250 7.3 started to chug then died. I pulled over & it started right back up. I did some running around & was on my way home & it did it again only this time it would barely idle (same chugging). It died again & now it wont start. Turns over strong.....
View 14 RepliesSo running into an issue with boost numbers. Factory gauge reads between 20-30lbs on throttle, but I have a SCT x4 and it only reads 3lbs and at idle it only reads .25-.89 somewhere around that range. Are these numbers accurate?
Also, it has developed a sort of buck or chug at like quarter throttle while accelerating, it's sluggish leaving stop signs etc. and it sounds like the waste gate or blow off it holding on even after I let off of the throttle.
I've got an issue with my 92 2.3 ranger.... sitting at idle for 30 or so seconds it starts to chug and sometimes dies.... I can hit the throttle and its fine for another 30 or so seconds.... while cruising on the freeway after about 30 minutes it starts to cut out badly... let out of throttle for a few seconds and it clears up and drives fine...
Here's the part that has me confused... pulled codes yesterday using a innova scan tool...
koeo were 4, 10, and 538...
koer were 111, 10, 157, 158, 181, 327, 328, and 334....
How does it give me a 111 pass code and then still come up with all the other codes? I am thinking my ecu may be screwed.....
I have a 2005 Ford Sport Trac that was getting 15 MPG on the highway so I decided to give it a new set of plugs to see if it would work. Wrong now I get 13MPG on the highway and by all topics I have looked at I should be getting 20-21 MPG highway. It is a V6 with 141,000 miles on it.
