Guys,

i have exprienced some weird shaking with the car .. all these shaking happened when i was traveling to and from vermont .. this shake would happen at speeds of 70+ .. but not at one particular speed .. it varies all the time .. and a P0300 CEL would come on right away after the shake .. the shaking is a weird vibartion and the car would feel like its losing a cylinder or to that effect .. so i thought it may be the plugs, so i had that replaced and the problem is still there .. does anyone know what this can be ?

and also, this problem occurs even after i upgraded my turbo, mani and 02 housing .. so its not from the turbo upgrade ..

i have run to vermont every winter since i got the car .. and this is the first time i am getting this weird vibartion .. can anyone help ? thanks

most recent mods done right before is Sun Auto Cyber Speed Hyper Voltage system and Sun Auto Hyper Force system .. would i need to replace my stock plug wires ?

 

do a search on the p0300

 

i know what a P0300 code means .. i've got that code before and it never shake the car like it does now ...

 

That happened to me a few times within a few minutes. But thats all. Never happened again. It also happened to me only at highway speeds.

 

thats what im getting .. once the car starts to shake .. i back off the pedal and get back on it and it will go away ... but once in a while during my vermont trips .. this has happened going and coming back ....

 

check cables
