I check the engine code and it flashed 7 times, my car is running at only up to 3.5k rpm. What do I do

 

Its in limp mode. Dont drive it much.

code 7 is Throttle Position Sensor (TPS)

 

I been driving it since November in limp mode

 

good way to ruin your engine

 

Well when you're broke and nobody knows how to fix it and it's your only car. You have to do what you have to do.

 

not that hard to find out (google) what codes it throws...

try to clean & calibrate your TPS or then buy new/used oem sensor

 

Just to be on the safe side, can you find a place to pull the obd2 code? If it's really the tps it's likely a wiring issue. In the faq's stickies at the top of the forum is a way to test the tps and how to calibrate it if you need to buy a new one.
