missfiring
Hey ppl my car is still missing on all 6 cylinders iv put in new plugs leads coil packs had it pressure tested ect cleaned out the throttle body put new vaccum hoses on it checked the fuel pressure and thats fine yet it still does it does anyone no what it could be ?
The V6 is MACEd
Are you 100% sure it's a missfire and not some vacuum leak or something making it sound rough? Make sure the hoses of the throttle body go into where they should. One at the back of the motor and one into the manifold. Also, maybe dirty/clogged injectors.
Im 100% sure its a missfire iv also double checked those hose on the throttle body and the ones at the back of the motor with no result ? Could possibly be injecters that about the only thing I haven't done but if it was missing on all 6 wouldnt the car just not run ?
i had recent problems like this in my VY and it was ratss to be the cause and if i was you i would check that all the injectors are in place and that none of the wires are damaged or cut and to go over your whole care and check that no wires or hoses are out of place.
After unclipping the maf and starting the car my computer comes up with tcu error is that normal ?
