TBI Hesitation
Hello all! I have a 1989 Grumman Olson P30 with a TBI sbc 350. For some time I have had to let it warm up until it reaches running temp (190) before I can drive it without it spitting and sputtering on takeoff. Once it warms up it does alright but I think it could do a lot better and it seems if I could pinpoint the cold hesitation the overall performance would improve as well. Thanks in advance for any ideas!

Tune up doesn't help. I was reading yesterday about the engine temp control switch and the MAP sensor as being possible culprits. I ordered both and will give them a try soon. If those don't help I was thinking fuel pressure regulator?
