Why does my car lose power when I step on the gas?

“Car makes only 1 click sound and electronics go black simultaneously.”source ↗

“Battery keeps draining.”source ↗

“Nothing I've done so far has changed how this car is responds, let alone fixed it. This has me as well as everyone else I've spoken to about it completely stumped.”source ↗

“I notice that I can hit the gas, there will be severe throttle lag before it gets going. On top of that, the RPM seems to stay low even at high speeds and it feels as if the vehicle is dragging something.”source ↗

“The CEL is on for P0420 and P0430.”source ↗

“My 1993 Subaru legacy with 208000 miles struggles a bit when going up hill and the rpm’s go into the high 3-4 and depending how steep the hill is or how long I’m going up hill for the car dies but it always starts back up and I’m pretty sure my brakes are sticking and that could be part of the cause, I’ve already changed spark plugs, battery, oil, fuel pump and the fuel filter”source ↗

“I hydroplaned really bad the other day and my check engine light immediately turned on and started stuttering like crazy when accelerating and I have no idea what to do.”source ↗

“When accelerating my car starts stuttering between 2nd and 3rd gear. it’s not every time I accelerate but almost every time.”source ↗

“what happened was as I was 5-6 meters behind the slow driver but already in the next lane next to them, the acceleration abruptly stopped and car started to accelerate then cut sharp multiple times in 1-2 seconds”source ↗

“Then as traffic let up, I stepped on it went from 18->20mph and would not accelerate further.”source ↗

“from a stop I stepped in it. It accelerated slightly slower than normal, then at 20mph hard stop on accelerating and would bounce revs.”source ↗

“It still shifts up, just not if I floor it. I cruised home going 65mph at the normal rpm”source ↗

“Along with the new noise, I’m also getting a feeling that something is holding the car back while driving, almost as if something is stopping/resisting the car.”source ↗

“My AC went out recently and since I got it repaired, the vehicle has had issues going uphill, but also issues with acceleration and runs a bit higher RPM than it used to.”source ↗

“My gas mileage is now about 6-8 mpg worse than it had been.”source ↗

“I keep having to rev the car to get/keep speed at highway speeds.”source ↗

“What would be the signs that a VTEC solenoid is broken or clogged, because i noticed that my R18 Engine runs weird, i know the r18 vtec works differently but when i try to floor it, it struggles to go to like around 4k rpm”source ↗

“and i notice that whenever im normal cruising the rpm would drop and would struggle to climb”source ↗

“Is your car jerking when you hit certain speeds? I remember mine would jerk violently at about 30-50 mph when it had the bad VTEC Solenoid.”source ↗

“Will a odb code reader help pinpoint the problem? It's a 2012 Toyota Camry”source ↗

“Mondial SMXE 125 (2022)doesn’t want to gain speed unless you cycle through all the gears and maxes at like 30mph. Bogs in all gears but revs pretty fine in neutral.”source ↗

“Now that i had the new transmission installed, the car feels heavy (in a good way) but the response is a tad slower than before.. is this normal?”source ↗

“I got a new battery but now my car doesn’t accelerate.”source ↗

“It doesn’t accelerate at all. It starts and there’s no codes showing at dashboard.”source ↗

“it drives well when cold, but after it warms (or a hot day), it will refuse to accelerate under any sort of load.”source ↗

“After driving around for 20 minutes or so, once again it stopped accelerating when really pushing the gas pedal all the way down, topped out around 30mph.”source ↗

“It seems like the engine is being choked out under any sudden load. I have to baby the gas pedal to get to 40mph”source ↗

“Car drives at like 30mph and does this stuttering if put my foot on the gas to fast.”source ↗

“my w204 did same thing once, scared me half to death”source ↗

“I was backing a newer benz up in the lot and it jammed the brakes on because of a parking curb. I thought I hit something when it happened.”source ↗

“Was driving the Vehicle on the highway when the car suddenly had all these emojis turn on.”source ↗

“In addition to this, the vehicle is also having trouble accelerating. I could step on the petal and get stuck at 40.”source ↗

“My issue is that it cannot climb hills, driving through a mountain pass or through rolling hills of Oklahoma it's all the same, slowly losing speed and downshifting until I'm doing 20 mph on the shoulder with my hazards on.”source ↗

“After about 40 minutes of driving, it begins to cut back and lose power. Drives fine before that.”source ↗

“After about 40 minutes of driving, it begins to cut back and lose power. Drives fine before that.”source ↗

“A new Maf sensor didnt help much, so I'm putting on an O2 sensor (upstream) tomorrow.”source ↗

“It only starts doing it after a 35-40 minute drive. Idles and runs fine in the morning when I leave.”source ↗

“Yes and it is leaking oil , and when I go up the slightest hill it will not go more than 20 mph and it sounds like it is running real rough”source ↗

“The mechanic installed original back and ever since I lost acceleration after 60kmh my rpms are lower by 100 to 400rpm.”source ↗

“For example 100kmh is 7250rpm while before it was 7500rpm.”source ↗

“This car has died on me in the middle of intersections 4 times and the bhph that I got it from can't seem to figure out exactly what's wrong.”source ↗

“It loses significant power when locking the steering.”source ↗

“I mean, it nearly dies way too often for me to be comfortable.”source ↗
