Conversation Between frederic and sean.mahler

hi i have a few questions to run by you and see what you think. Finished install on a 1990 302 and start engine and it seems to have a miss and surges has low vacuum 14 i have no vacuum leaks i have checked and re checked. Timing is dead nuts on 10 btdc with spout removed replace spout no change wire is good all the way to pcm pin 36 i omhed it map sensor reads like it is supposed to but i think the vacuum pulls through the sensor waiting on new sensor to verify any ideas wood be great
