Re: 93 caprice has hunting idle/ hard to start when cold
I know you've replaced the fuel pump (and hopefully the filter), but did you test the fuel pressure? Your symptoms are typical of low pressure on a TBI220. The regulator (on the rear of the TB) is suspect.

Re: 93 caprice has hunting idle/ hard to start when cold
I replaced the fuel pressure regulator also, I don;t have a guage to check pressure but everything but the fuel lines and tank itself has been . could my timing at the distributor/ HEI cause the problem?
