    Tbi 350 has no power on the road

    Part of the reason I was so frustrated with it was because I measured them all with the rockers on, and they kept bleeding down, so not one I was confident with, so I took them off, and now I'm confident. The worst part was setting up the cheep Harbor freight tool, keeping the pushrods straight...

    Tbi 350 has no power on the road

    OK, so my distributor is on correctly, looks just like that picture that L31MaxExpress posted, I got a CHEEP dial indicator from harbor freight, it's junk, it takes so long to set up, I did the entire left bank, and really don't want to do the right, it's just so frustrating setting it up, and I...

    Tbi 350 has no power on the road

    The plug wires are no my issue, the previous owner put brad new ones on, and I threw a set on I yanked from a 95 I have in the weeds, no difference, I also power braked it, to make it run like ****, and did a cylinder deactivation test, to find out that I am not chasing a missfire, it's fireing...

    Tbi 350 has no power on the road

    Firing order is 100% correct, double, triple check every time I hook up wires, exhaust doesn't smell that rich, maybe a tad gassy but I've smelled worse... I have no engine noise to speed of, honest sounds very healthy, I can pick up a dial indicator this week and check my valve lift, found on...

    Tbi 350 has no power on the road

    The distributor was off a tooth when I got it, but it was adjusted enough it really didn't matter, the wires going to the coil were tight, I put it in correctly and set base timming to zero

    Tbi 350 has no power on the road

    Already done that, that won't tell me if the cams warn, that tells me the valve are sealing, but if it doesn't open far enough to alow enough air through is where my heads at...

    Tbi 350 has no power on the road

    Humor me, what would a warn cam/lifters act like? Thinking maybe the extra fuel is from not enough air, say my intake valves are not opening as wide as they should... idk, is it worth pulling the intake to have a peek at the lifters? It revs up just fine in park or neutral, will red line and...

    Tbi 350 has no power on the road

    Looks to me like I'm going mad rich when the problem happens, assuming of misfires I stuck small chunks of wire under each spark plug boot on the distributor, and wile I had someone power break it, grounded each one out one at a time. Each time i can tell the engine was loosing a cylinder, so it...

    Tbi 350 has no power on the road

    Here's some data from a warmed up engine that was off for a few minutes then restarted, that knock deal I can not get to go away, I currently have the wire for it removed from the pcm pigtail, also the replacement pcm I got from the salvage yard wasn't giving my MAP 5 volts, so I can't trust...

    Tbi 350 has no power on the road

    So for now I still have a different throttle body I had from a 91 gmc k1500, so it's the same year and same size engine, buy switching the entire throttle body I wanted too rule out fuel pressure regulator, because I had to order an adapter my fuel pressure gage kit didn't have. Also ruled out...
