Spring is in place and all linkage looks the samne as my other w123 but the car stays stuck when i hit the pedal,today i was able to turn it on without it going to high rpm's but as i was going out of the garage as soon as i put a little gas it stays stuck,i checked the pedal and i was able to release it from inside the car by pulling a bit on the gas pedal? what can be causing this?
