1987 Suburban TBI not running right.
So my 87 Sub has been hesitating when at partial throttle or when climbing hills.It doesn't do it all the time most of the time when it does it is like it isn't getting gas for a sec.Other times it backfires through the TBI.
I changed the fuel filter and the fuel pump is a GM one that is like 5yrs old.I did the carb cleaner trick and found the base gasket was leaking air in.Replaced it. It is not throwing any codes.I was thinking Mas sensor or TPS.I don't just want to throw parts at it.Thanks in advance.
