Filed May 20, 2018 · Acceleration · 86,000 miles · ID

While driving the cars check engine light will show up. I lose all control of speed even while pushing the gas pedal in. The only way to regain control is to cycle the key multiple times and let it idle in neutral for five minutes. After I regain control the check engine light is still on, and the car will jump revolutions randomly. This will occur on both city and highway speeds, it doesn't act up unless I'm in motion driving. It will rev I'n revolutions while I'm driving or at a stop.

I have had the transmission range sensor replaced on my 2008 suzuki forenza twice already and it has malfunctioned again. When it malfunctions, my car jerks heavily when changing gears, and it is an automatic engine. The rpms will not exceed 3000, the check engine light comes on, and "hold" flashes in the dash. The car accelerates very slowly shudders above 50 MPH. The speedometer has dropped to zero while I have been driving on the highway, so I cannot tell how fast I am going.

The "trans range switch" is causing my car to jump to 2 gear randomly. The car seems to run fine after o start it. And out of no were the engine jumps and the "engine light" comes on the car acts likes its not in 1st gear. It can't get it to go into gear (drive or reverse) without it jumping. Then after the car sits for a day it acts fine for the first trip and then it starts the same problem again afterwards. I can't go uphill either without it reaving high like its in neutral. I think this is the "trans range switch" going bad.

I bought my car used and it has a new tranny, cv axles and everything the only thing original is the engine. So I have already had to replace the o2 sensors twice at $60 each. I have had to replace the tps sensor, thermostat and housing, ignition coil, battery, starter, fuel pump and alternator. All because I kept getting the check engine lights on and throwing coding all over the place. And the car still stalls when I stop at a stop light and runs and idles rough. I have spent over $1500 fix this problem and it still exists I did all the work myself I have worked on cars my whole life and am a mechanic. Every mechanic I take it to can both find the problem and suzuki can't give an answer to the problem and I don't know what to do.
