Power and acceleration problems

Jerks and accelerates suddenly SolvedSolved

Chevrolet Equinox 2007  85000 miles
I bought an Equinox 2007 two months ago and it has already presented many failures. The one that worries me the most is that, when driving on an uphill road and over 40 mph, it is really hard to speed it up. When I try to overtake another vehicle and hit the accelerator hard, a forced engine sound becomes audible, the speed goes down and it suddenly starts with a hard jerk, more like a kick. Another thing that happened to me yesterday was that, after fuelling the car, I turned the engine on and the steering was really hard, to the point of not being able to turn the steering wheel. I turned off the car and on again and, luckily, it started working normally again.

I had this problem and I changed the main flow and it was solved. You should as well check your accelerator.

In my case, I changed the valves body and it was the solution to the problem.

Mine did that. It would slow down and then all of a sudden speed up and audible noise from the engine. It was the timing chain. Have had it replaced 3 times.

Could be simple as a bad throttle position sensor or as complicated as a bad timing chain

I had the SAME EXACT acceleration problem. No check engine light either. $3700 in repairs/parts... even a warranty covered replacement transmission...still had the same problem. after 6 months check engine light came on. Turns out front catalytic converter was well beyond repair . The front catalytic converters in these cars go out well before the check engine light comes on making it hard to diagnose

Jerks SolvedSolved

Chevrolet Equinox 2007  88000 miles
When driving at 40 mph or more, the rear tires jerk. I try to speed it up but it won't accelerate. Might it be the transmission? Thank you in advance.

Change the spark plugs' wires and the jerk will stop. I recommend you to but Gargol's wiring, it is better than the agency's.

Thank you very much Ree for your comments. I will now change the wires and see what happens.

Jump in rpms

Chevrolet Equinox 2005 2005 Chevy Equinox 102445 miles
I was parked just idling, all of a sudden the engine revved up to 2500rpm but then came back down to normal. Then my engine light came on. What would make this happen?

Misfire. Check spark plugs and wires. If not check egr valvue.
Inkman66 from Canada 4 years ago
Sounds like a throttle position sensor issue

Same problem for me. It was the front catalytic converter needed replacing. Problem solved

Car cranks starter spins but does not start the engine

Chevrolet Equinox 2011 AWD 6 cylinder  95000 miles
My Equinox has been running rough last 2 months when you hit the gas to catch up to speed it boggs out and then eventually gets to were it needs to be but a lot of times when coming to a stop it stalls out I put in neutral and it fires right back on long story short it last stalled in my driveway 3 days ago and in my opinion it is possibly some sort of electrical issue or gas issue i did go get the starter checked and it's fine so help me please lol

2016 equinox lt 2.4 (no nav) from United States 3 years ago
I had that problem intermittently as well for about 2 weeks I ended up replacing the starter relay, & fuse fuel pump relay or fuse whichever it called for then I replaced the battery and alternator then had my computer reset it's been almost 3 weeks and I've now had no issues cranking it up. Now the mylink is another story ps. I've heard that the 2.4 model has a oil consumption problem and a problem with the pistons getting clogged especially if your using the eco mode regularly. My 16 equinox lt 2.4 has about 78000 miles on it I have had so many issues and will probably be trading it in ASAP
Jaya from United States 3 years ago
It's the front catalytic converter dude. I've dropped $3700 in repairs to come to that conclusion....and it worked. Speaking from experience. The oem go bad unusually early (50-60k) and don't throw a code until it's completely too late.
Chelbi from United States 3 years ago
Yes I have the same issue , it’s prob an electrical fault . Order a code reader (OBD) and turn key on 2 clicks , pull up codes and clear them and then it should fire right up and sometimes when the battery goes dead it takes a jump with another car for like 20-30 min and it’s a process let me see if I can find instructions to post for you but I have to have an el truck source ( jump with another car ) and or full battery to get it going and reset the anti theft then it will start , the only other reason would be if it needs a new crank sensor or cam sensor

Jerking in gear at stop

Chevrolet Equinox 2013 AWD, Automatic 198000 miles
My car keeps jerking while in gear at a stop sign or whenever it’s not in motion. While moving, it changes and selects gear normally without jerking. This happens only when stopped. What could be the problem?

Does it diesel when you turn it off? Has it lost power? Pull your dip stick and check for gas smell. If any of these apply. Probably your hp fuel pump. Mine did that. It’s the fuel pump on the engine. Not in the tank. It’s a $900 fix. Easy fix if you’re mechanical. $200

2023 was a bad year

Chevrolet Equinox 2023  141000 miles
I had a 2023 Equinox as my work vehicle. After driving it a while, it would just lose power and die. After about 10 minutes, it would start back up. The dealership told me that it was the turbo booster. It would heat up and shut the car down. Most of the time I have worked for this company I have had all chevy vehicles. The last really great equinox I had was a 2017 and I never had it go to the shop. After it reached 125,000 miles my company sold the car and my niece and her husband bought it. Drove it for several more years after being transferred to Germany and sold it there. The worst problem was when we took the 2023 to the shop, the check engine light wouldn't be on by the time we took it in and there was no code to read so they didn't ever do anything to fix the problem.

Lose power when stop

Chevrolet Equinox 2017 Equinox 500345 miles
So, we replaced the battery and spark plugs, and it started running again for months. However, it would start again as soon as it went into idle, and it would die. When I was at a stoplight, the only way to keep it running was to park it and keep the throttle on. Also, when I plugged in the code scanner, nothing would pop up. I still owe $13,000 on the car, so getting a new car isn’t in my favor.
