My 1998 Toyota Tacoma Prerunner V6 is vibrating heavily when it is at a stop but doesn’t do it when it is going so I know it is not the tires or shocks. So what do you think is wrong with it because I took it to three certified mechanics already and they said three different things. The first one, I let him change what he thought it was which were the Spark plugs, all three ignition coils, and ignition wires but it didn’t make a difference. So on the other two I went to, I told them that I will get it checked by another mechanic to confirm the problem. So the truck has a brand new ignition system and yes I used genuine Toyota parts which he ordered from the dealer. The second mechanic said it was the fuel injectors are clogged and has to be changed and the third one said it was the mounting of the engine. So after the first one I didn’t let them change anything because it will cost me a lot of money buying parts that I do not need. Please I need your opinion on what is wrong with my truck. Thanks.
