Citroen service for 307

(30 thousand 1.6 triptonic lpg with 99 thousand) In the morning, it was as if something was broken, the sound didn't sound and the car started to shake. The converter gave a fault error. I pulled right. I switched to gasoline, the same problem continued, I hardly came to work and parked at noon, run it, no problem, I tried it on the ramp, I pushed it, there is no problem. In general, I am comfortable, I will go to the pejo service, but I do not trust because I have done all the maintenance last week. . (this & nbsp; weekend & nbsp; & nbsp; I have to go out of town for a good job, so I have to handle it tomorrow brothers)
