I had a very similar bucking to you under load and it turned out to be a loose connection at an earth point on the engine block... it’s the one you can’t see under the plenum on top of the block... have you checked here??
It’s the earth for the injectors so if it’s bad under load it only gets half the power it should have... bucks like crazy. If you haven’t checked here, please do so. Very similar symptoms to a bad TPS and I changed that too and it made no difference. Happened across this earth and bingo. |

Good idea to check the grounds. I have a set of known good injectors coming and I'm going to try those too.

So I towed the car to Brad 914Ltd. Turns out the timing was way off, he rotated the dizzy and all is well.
I still don't understand why it started running poorly. I put in the LED taillights, kept the ignition on to check the lights without starting the car, thought I burned out the Pertronix, replaced it with new Pertronix, replaced the fuel injectors and it continued to run like crap. All is well. As usual, you guys are the best for taking all the time to help me figure it out. Next time I'll start with the basics!!! Paul |
