I have an 83 El Camino and just had a set of headers installed by a local shop. For some reason the engine
is now misfiring and I tried contacting the shop but the mechanic left for vacation. It has a 305 engine and 1 thing I notice is that there is a vacuum line hanging on the passenger side of the motor leading to the 4th port (going from right to left) on the carb. I have tried putting my finger on it but seems to have zero effect.
JA: How many miles are on the car? Is it a steady misfire? Or random?
Customer: Doesnt seem to misfire when in park but in drive it will misfire and also when I put it in reverse, it stalls.
JA: What is the make/model of your car?
Customer: 83 El Camino Base Model.
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: Replaced plugs on the driver side and wires, plugging hanging vacuum line from carb.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Not that I can think of.
