Infiniti - G35 :: 2003 Slows Down While Accelerating
Feb 29, 2016
My G35 has around 115,000 miles and it slows down when driving, particularly when driving uphill. RPMs reach 2-3 and car begins to drag with an occasional jerking. I've replaced all spark plugs (don't think I've ever replaced them since I bought the car used with 40,000 miles) and I notice one of the coil packs and its spark plug was oily, but then I also notice it was not connecting to the spark plug like the rest the rubber tip was ripped. I replaced the coil pack, but the issue still exist. I just got back from a test drive and this time it doesn't lose speed so much, but still trembles, especially when going uphill.

I tried going up the driveway and as I was accelerating, I almost noticed a little "slowing down" while trying to accelerate up the driveway. It was really snowy so I am thinking that it might have been the ESC trying to fix the path. I thought about this after I got it up the driveway, so I couldn't test it.
Is this normal or should I have it looked at by a mechanic???

car makes a noise like a jangling bracelet when I press accelerator. Doesn't make noise while idling.

I drive a '96 Infiniti I30, and recently the driver's side front wheel has started making a mysterious noise. It's not a grinding but a clicking/clanking noise. It's only present when I'm turning and accelerating. If I let off the gas it disappears. The other strange thing is that i can feel it in the gas pedal. I looked at some other discussions and the only thing that was similar was a bad CV joint. One last thing, if it is the CV joint how soon should i get it replaced?

I have a 2001 F650 7 speed with 7.3l powerstroke and I am pulling a 15,000 pound fifth wheel. It is very new to me and just doesn't seem to have the pulling power. It seems to struggle even on flat going 65mph and when it comes to hills it really slows down. Should I be looking into power chips? If so, which one? Is there something else that may be preventing the full power?

Recently noticed a hissing noise coming from the passenger front-side of the engine compartment (alternator area). The noise only appears when the car is warmed up and revved to over 2k rpm. At that point the hissing starts and does not stop even when idling. As soon as the engine is turned off (even when warm) and re-started the noise is gone (until 2k rpms).

have a 2003 infiniti m45...was showing the battery light; co-worker tested with a ohm meter and the reading was 12.5(before stalling); suggested the alternator was bad. Just replaced the alternator and now the ignition won't even turn over(dead as a door knob)...before the change, removed the battery(which is dead by now), followed the steps and now I'm dumbfolded...what could be wrong?

Our '03 Infiniti I35 lost large amounts of coolant each time on 2 long trips but when we did a pressure check, we couldn't get it to leak anywhere we could see and no visible signs of where it may have leaked while driving (no drip lines, puddles, etc.). We're not sure where the water pump is located, but have been told it's internal to the engine, so how can we tell if it's gone bad? Would the coolant burn off with no visible signs? We changed the radiator cap but no change. We use a trusted shade tree mechanic, but he's stumped.

Noise occasionally comes from the driver front wheel on acceleration. Can not be duplicated when a technician looks at it.

For those of you that own both a TCH and a 2010 Prius I have a question for you. My commute is only 6-7 miles to work and currently I am getting approximate 45mpg displayed on the mfd. I think I read somewhere that the display calculations may be a little high but all in all I am very happy with my mpg. I am considering trading my 09 TCH for a 2011 or possibly 2010 Prius if the price is right. Anyway If I accelerate my 09 TCH to approximately 41 mph and take my foot off the accelerator, when the car speed slows to about 38 to 37 mph the engine will shut down. I can now lightly push the accelerator to drive along just using the battery. If on a flat road or a slight down hill grade I can even pick up speed and get to about 41 mph before the engine starts back up. My question is how does the Prius work the same way? What are the speeds for the Prius?

My transmission bumps every time it slows down to 30 mph, dealer said needs to be rebuild.

I own a Chrysler 300 touring. It's 2006 and its automatic transmission. I was driving on the highway and I reached 60mph then I heard a sound and a rough push and suddenly the car started loosing speed. It didn't loose power. Luckily I was getting off the highway and turned on the hazard lights, I made it into a neighborhood and let the car reach 0. When it did I pressed on the accelerator and it started moving.

I have a 05 Sprinter 6 cyl gas HD that overheats a little at highway speeds over 60mph and then the rpm is limited so the van slows down to the 50 mph range even if I floor the gas peddle, I usually pull over turn off the engine and let it cool down for an hour and resume the trip. It only does that when going up the mountains while the van is loaded or on extremely long trips. Ive taken it to two mechanics both could not reproduce the problem. It has 250k...

Ok so this one is pretty hard to explain. I was driving home from school, doing about 55 in fifth gear. Out of no where, my car started to bog very hard and slow down. I pulled into a lot and as I was in the entrance of the lot the car haulted itself but stayed on. I say there for about a minute, then put it in 1st and drove into a parking spot. I stayed there for a little, then drove home in the right lane and it seems to be back to normal. I also did a few test pulls and it felt a little laggy but that might just be in my head. It's a 2012 golf r, 37k miles with just an EVOMs intake. Stock otherwise. What this could be? Don't want to get stuck on the highway somewhere if this happens again.

Alright here comes another head scratcher, the car has no check engine lights, no oil is leaking, and all of the liquid levels are at their normal readings. The problem I am having is the car feels like it is dragging a bit, as in it takes a bit to accelerate and as soon as I lift my foot off the gas it drastically slows down.
Talk about 0 to 60 in 30 seconds and 60 to 30 in 5 seconds. Now what I have noticed is every time I pass a radar detecting sign, to make sure you are going the speed limit or slower, which in this case it is supposed to be 25 mph, my speedometer will read 30 to 35 mph, but the sign will state I am going 23 or 24 mph.
I know the detector is working because I tested it with my dad's Buick and while the Buick stated 20 the detector also stated 20, I know what you are saying maybe it's just a fluke, well I tested the detector with my brothers cougar, my sisters Honda, and my friends Chrysler and they all stated 20 both on speedometer and the detector. I have changed the spark plugs, the ecm, the ignition coil, the spark plug wires, starter, the valve cover gasket, hoses that were broken, the speed sensor, cam shaft position sensor and it passed the state inspection.

I have 1995 Dodge Neon (automatic). Lately, after long trips and on the highway the "check engine" light will come on. Then, the car seems to struggle shifting. I will be cruising along at like 68 MPH, then ease my foot off the gas to slow down, and the engine/car awkwardly jerks 2-3 times as it slows down. Trying to stay in the 60-70 MPH range is hard because is keeps hesitating and jerking as my speed changes, not HEAVILY but enough to make driving unpleasant. My cruise control stopped working about a year ago, I have not had it looked at yet, but I thought I should mention it. When I let the car rest overnight, the light goes off, and there is not problem until I go on a long trip again (around 200 miles.) This only happens at higher speeds, around town there is not a problem.

I have an '09. Experience a shakiness/shaking when the car slows down to a stop? Like, you slow down to a stop, then the car starts to shake for a few seconds.
I feel like it doesn't happen to me in neutral, which makes me think it is the transmission. Sometimes I get a rough/shaky start as well....

Only have driven 2900 miles and engine frequently misses when it slows from 40 mph down to 35 mph. After a test drive dealer told me that car is handling normally. Can't be true. I consistently get a "lagging" feeling whenever I slow down from 40 plus mph to 35. My foot remains on the accelerator with just a slight decrease in foot pressure. I'm returning to dealer next week and I don't know what I will do if they tell me the vehicle is acting normal.

I recently purchased a 2012 used Santa Fe. I've only had it about 2 weeks and just noticed something the other day. When I shut the vehicle off and exit, I hear a very low ticking noise coming from behind the front grill vents. It lasts for about 15 seconds and slows down until it stops completely.
I'll be the first to tell you that I know absolutely NOTHING when I comes to cars (other than how to drive one ). My guess would be that it sounds like some type of fan coming to a stop. If this is the case, I'm wondering if one of the blades could be bent, and how potentially serious of an issue this might be? Other than that, it drives great, with no other notable noises while in motion.

My 2006 Sonata GLS headlights dim along with the entire lighting electrical system when my car slows down past 1500 RPM. Why??? I had the car worked on 2 weeks after i got it because of this and they replaced a timing chain thinking this was the problem, but it wasn't.

I live in a community with a posted speed limit of 15 mph. I travel a full minute at 15 mph before I exit the community to a city street. My 2013 Accent Hatchback won't "glide" along at 15 mph. It jerks and surges and races and slows down. I've tried using the manual option and keeping it in 1st gear however, when I reach the 1st gear tachometer limit at 15 mph the car "stalls" and the tachometer needle drops out and the car slows to 5 mph.
