2006 Suzuki Forenza
I can't drive it and drive it shifts hard don't know exactly what's wrong with it I need ideas ??

The Suzuki Forenza got a significant makeover for 2006. Key changes included a new grille, reduced emissions, and higher quality interior materials. The number of trims goes down to 4 from 6 the previous year. This '06 version of Suzuki's budget compact sedan comes as a Base and Premium Sedan and Wagon.
Gas mileage averages out to 22 mpg in the city and 30 on the highway. Unfortunately, the 2.0 L, 126 hp I4 engine with standard 5 speed manual transmission and optional 4 speed automatic just doesn't quite cut it in a market where the V6 carries the day. All 4 trims have 4 doors, seat 5, and have front wheel drive. Standard features include air conditioning, power windows, power door locks, and cd player. Premium trims have optional sunroof.
Overall, most drivers reach the consensus that the 2006 Forenza delivers enough features for an affordable first car. Otherwise, the lower class materials and occasionally rough ride present only a couple of the many issues consumers encounter with this compact. Suzuki's slogan for the Forenza says 'It's gonna be a great ride.' If you're low on cash, this model will get you by until you earn enough to make the slogan a reality.

I took it to autozone and they say it's the injectors so I changed them but it still won't work
i have i 2006 suzuki forenza with 102000 miles and just recently my transmission started acting up. I tried to pull away from a stop light and it took more acceleration than normal to go. Then i realized the check engine light was on. Not sure if it's stuck in a certain gear or not but it doesn't shift. i was going about 55 or 60 at about 3000 rpm's when normally it would only be about 2000. At first i thought maybe it could be low on fluid, but im not able to just check the fluid since there is no dipstick. It also shifts hard when going from park to reverse or from neutral to drive. It does start and run just fine so I'm not sure if it's a sensor. Is this my transmission beginning to burn up or (hopefully) a simple fix that won't cost 3000 or more dollars to fix?
So I was driving through typical friday bay area traffic when I noticed my car failed to accelerate when I stepped on the gas pedal. No matter how far I pressed down on the gas pedal, the vehicle failed to accelerate, nor was there an increase in RPMs. RPMs hovered around 1200, with an occasional spike of around 18-2000. The vehicle would slowly build up speed to about 20-25mph. When I finally coaxed it to a stop at the house, I turned the engine off, and turned it back on (I'm more of a tech guy, and I figured the reboot trick of most computers was at least a worth a try). Sure enough, everything worked fine. Or as fine as my broken car had been running. I can't say if a check engine light came on or not, as the CEL was on previous for a failing throttle position sensor (has it finally gone out?) and a bad break light switch. So, my question is, what do you think is the issue?
