Prius (2004-09) :: Gas Pedal Too Hard For Acceleration After Spark Plug Change
I have a 2007 Prius with ~180000, which runs great. The mechanic shop I used for oil change suggest me to change spark plug because they are dirty. After the change, I found I cannot step on the gas pedal too hard for acceleration. The car will hesitate, choking or die if I try to accelerate too fast. But if I step on the gas pedal gently, and let it reach the desired speed in a slower way, it has no issue. I went back to the shop and they replaced with another set of 4 plugs, and no improvement. I checked air intake tube and it looks no leak, but really old. Other than that, the car runs great.

I went to the local dealer at about 6K miles to get the free 5K service. The invoice said synthetic service, so it should be the 0W-20. Now the average mileage since the last fill-up is lower by at least 3-4 MPG. My driving habits haven't changed. I inflated the tires to above 40 PSI. I looked at the oil. It is medium amber colored. (I forgot to look at it before the oil change. )

Just had my 20,000 mile service yesterday on my Prius Plug In and got 10-15mpg loss in gas mileage today. It seems like ECO mode isn't even working anymore because MPG just drops to 15 MPG when you accelerate pass the half way point.
I'll take it back to dealership tomorrow? It should have only been a oil change and oil filter change. Reading some old threads makes me thing they put in the wrong oil?? It says 0W20 on service contract but not sure if correct.

I just changed the plugs in my 05 stx 4x4 4.6L. Truck was running fine, never a problem but it has 105k so I figured id change them. #4 was the only one that gave me a little problem (besides being so tight). The coil and spring pulled off the boot, and I had to get a pair of pliers and get the boot off the plug.
I simply slid the spring back through the boot and replaced it once I had changed the plug. Other than that they all came out easily. I replaced with motorcraft plugs, and #5 did have what looked like some oil down on the threads when I pulled it out, but not sure if that's a big deal or not
Any way, I am torn between ordering new boots and changing them out, or just biting the bullet and getting 8 new coils with new boots attached. Truck runs fine, but does the usual buck/jerk under a load in overdrive now (never once did it before)...
Prius (2004-09) :: Mileage Dropped After Oil Change
I have an 05 Prius that I bought used. It has 59K miles on it. Recently I took it to the dealer for an oil change. They told me it didn't need an oil change, but did need an air filter. Afterwards, the mileage dropped from about 47 around town to about 42. Had the oil changed a week later, and the mileage is now about 40 around town. The dipstick when cold shows a little above the full mark.

i have a 98 buick century has around 180000 miles and it ran perfect, then two days ago i changed my spark plugs b/c they were 2+years old i got NGK Vpower and gapped them to .06. i had to roll the engine forward when i got to the back 3 plugs. so anyways after all pugs were changed i took it for a drive it was running fine, then i noticed when i got on the highway when i had to accelerate it missed a few times then on down the road it would go fine until i had to give it a little gas.
It jerks a little bit and it sounds like shit. But it idles alright and light acceleration thru town is fine. i also had it tested at autozone and i got a bunch of stuff about vacuum something and 02 sensor but nothing about misfire or coil pack malfunctioning. all the vacuum tubes on the engine are all sealed that i can see. and like i said it ran perfect before hand so i know its nothing internal. i just cant figure what happened.
Camry :: 2008 Toyota - RE Spark Plug Change
my wife drives a 2008 toyota camry 4cyl. she has about 86000 miles so i figured i would do a little tune up. change plugs, filters, injector clean, etc. while changing the plugs i seem to have broken 3 of the 4 pressure tabs on the plugs that plug into the coil. for the time being i have the pressure tap electrical taped very tightly onto the plug. What I should do? or is that common to for those to break off. I didn't even really use a lot of pressure either.
View 2 RepliesSanta FE SM (2001-06) :: Won't Start After Spark Plug Change
I somehow managed to kill my 04 Santa Fe 3.5 while doing the dreaded spark plug change and looking for pinpointing and rectifying the problem.
A quick rundown of the car... My mom bought her new in late 03, decided to get a BMW X3 a couple of years ago. I bought her with 65k miles. I just recently had the timing belt replaced by a reputable shop at 79k (yes I know I let it go too long.) I just hit 80k and decided it was also time to do the plugs as I had noticed a decrease in performance and gas mileage of late. Other than the recent dip in performance the car has been extremely reliable and has had no previous issues.
I researched as much as I could knowing that the 3.5 isn't the easiest engine to work on. I bought the recommended Champion plugs that came in the car from the factory as well as the oem Hyundai wires. I also replaced the plenum gasket.
I took my time replacing everything but despite my best efforts, I accidentally cracked the plastic on the radiator reaching over to the back bolts on the plenum. Other than that mishap, the only other issues was the #5 plug sticking which finally came loose after some begging and pleading to the car Gods. Unfortunately, my begging and pleading was enough for them to allow the car to start.
After reading a thread on here, I believe the problem is that I removed the TPS sensor to get to the bolts on the EGR valve, I know now that this was a big mistake. I checked and double checked every connector and can not find one that was missed or disconnected. The car would try to start but would not crank over. I was unable to get any OBD2 codes from my code scanner.
I decided to try a TB from a junkyard and swap it on to see if that was the issue. After swapping it on, the car started and ran like crap for about 15 seconds and stalled out. I was however able to pull some codes in this short time.
The codes I received are:
P0102: Mass Airflow Circuit Low Input.
P110 & P1172: ETS Improper Motor Current.
P1192: ETS Limp home - Target Follow Malfunction.
P2127: Throttle Pedal Position Sensor "E" Circuit. Accelerator Position Sensor 2 Voltage Too Low.
I'm not sure if these codes are left over from before I swapped out the TB or not. I reset the codes after I wrote them down and researched them to see if they reappeared but the car will not start again so I can't get the codes to reappear.
Sonata NF (2006-10) :: MPG Drop After Spark Plug Change
Just replaced spark plugs in my 2007 Sonata V6 and noticed that my MPG has dropped from about 24 to 19! I used NGK Iridium plugs, and also changed the PCV valve at the same time. Mileage is 136,000. Could the internal computer (that does the MPG calculation) have gotten messed up by all of the disconnecting/unplugging that I had to do to get the surge tank off? (BTW - the engine runs great - just the MPG went way down).

Continuing from this thread which I accidentally posted in the "main" forum.
I had trouble unscrewing the spark plug even though the advertised torque is only 13 ft-lb and the car is only 13K miles 1.5 year old.
I googled "spark plug stuck" and read some posts on line.
Lots of horror stories of broken spark plugs and stripped threads - big $ to repair.

View 5 RepliesFord Escape / Hybrid :: 2011 V6 Won't Start After Spark Plug Change?
I have a 2011 Escape Limited 3.0l V6 AWD. Did a spark plug change at 115k miles for the first time per dealership recommendation. Got new plugs from dealership.
Was pretty cut and dry to replace. Did not check gap on plugs as was told they are not adjustable per dealership. Put pea sized amount of dialectric grease in the COPs and then fitted the plugs into several times with a little spin to coat evenly. Installed plugs to 11 ft.lbs. and reassembled all components without issue. Installed them one at a time so as to not mix up the coils.
I did break the 90-degree nylon quick disconnect for the fuel line that connects to the fuel supply manifold and had to purchase a new hose assembly. Reinstalled without issue.
Went to start up and engine cranks (hiccup sound) but does not turn over. The sound is weak and not a throaty crank like an engine should give. Check engine light flashes on dash and issues a frequent tone also.
Wondering what the issue is? Are they the wrong plugs? Improperly gapped? Possible the fuel line did not pressurize and there is no fuel getting to the plugs for ignition? Kind of stumped as it was a pretty cut-and-dry replacement (if such a thing is possible).
Prius (2004-09) :: Main Water Pump Leaking / Oil In Spark Plug
I have a small problem, the dealer that serviced my car just told me that my water pump was leaking and I was low on coolant. I can't remember when was the last time I checked the coolant level but when the dealer top off the coolant, he nearly used the entire bottle. Needless to say, I believe the radiator was pretty low on coolant.
Now I've never noticed a high temperature warning lamp or ever broken down. Today at 125,000 miles, I went to change my spark plugs. The 1st plug to the far left as you are facing the car has oil in the spark plug. This is freaking me out, could my engine be damaged from the low coolant?
Lexus RX 2004-09 :: Gas Mileage Slightly Lower Than Normal On RX350
I had made a trip down to Branson Missouri for Christmas, which is about 1000+ miles round trip, and the milage seemed to be slightly lower than normal on the computer, about 23 mpg. I went to Iowa after that for Christmas and filled up my tank once when I was there, I was sure to get 91 octane gas. Then after doing a lot of in town driving it went all the way down to about 11 mpg. It jumped back up to 17.9 as I was driving back up to the Twin Cities and hasn't moved after doing some in town driving since then.
The tank seemed to match the computer as far as how fast it dropped, but I'm curious if there's anything I should be looking for. I have a K and N filter in there, and it's only been used 10,000 miles or so, but I cleaned it anyways, since there were some bugs and small leaves in it (there was also a large black spot on it that didn't look like dust or dirt, more like something oily, if that means anything). I'm planning on filling it up a couple more times and seeing what happens before I start going to my mechanic, but I'm switching jobs and will be driving it for work, so I'd like my vehicle to be running well.
