help me with tfs valve springs

[91foxbodygt]

recently took the car to the shop and they installed the tfs valve springs on my car. the car does not feel right. its shakes and does not respond at all. all i can think is that maybe they installed the wrong shims, any suggestions?

Since you had the work done at a shop I would take it back to them and have them look at it and tell them what is happening. If you started messing around with it and took some stuff apart and found a problem then they could possibly void any warranty on their work.

Good luck and hopefully it is something quick and easy to fix.

thanks bro,
yes i know but the guy from the shop said he did everything right. he said it was fine when he returned it to me, which is not true. so warranty is out of the question, he said he doesnt know what it is...
would the shims make the car act that much out of wack???

Did you give him the heads off your car or did they change the springs with the heads on the car? Spacers have nothing to do with your car running poorly. They just do them to shim up the springs for closing pressure.

are the rockers loud? GOod chance he messed them up when he torqued them down.

i gave him the heads and the springs and he installed everything

Only thing he could have done to mess it up is mix up the valves when he took them apart. It could be on your end putting it back together, bad intake leak, vaccum leak, lines not reattached properly. Do a compression check to see if the valves are leaking.

The only person to work on your car should be you, because mechanics always screw **** up. So take it as lesson learned and start tearing stuff apart till you figure out whats wrong

Did you get the whole TFS valve spring upgrade kit? With springs, retainers, locks, shims and valve seals?

If so the only thing that I can think of that he might have done with the valve springs is put swap the retainers for the exhaust and intake valves. In the TFS kit the exhaust valves have a different retainer than the intake valves do. I am trying to think back to when I put that kit on my 93 and think of anything else that could get mixed up.
