Thanks

check the plugs...worn out?

so only misses when warm, hmmmm..........so off idle it runs fine (basically above 1000rpm) so when it tries to idle it misses. recheck vac lines or sensor going bad, tps, cps, maf...does it smell like its running rich at all?

MAF was bad-intake air temp sensor. Changed it,motor idles much smoother,still misses when warmed up getting code 51 now
