89 5 speed stock 5.0 backfire
Hey wassup jus need some input on my car. When I purchased it a month ago it was doing the same issue. Everytime I accelerate like faster than usual my car I guess backfires from what seems to me the exhaust. It doesn't do it when I jus have it running and I rev it. It only does it when I accelerate harder than usual like going up a hill or passing another car. It does it on any gear too. I have changed the egr, maf, iac, cap an rotor new sparks and wires and oil fuel and air filter. The car was sitting in a garage for the past 7yrs before I bought it and like I said when I took it for a test drive it was doing this sputtering. Tomorrow I am gonna check the plug wires to make sure they are on in correct order cause when I changed them I did jus follow the way the old ones were. Lastly the car has the smog pump still on it with the belt running on its pulley but the hose that runs from it to the back of the head was broken so I jus eliminated it and bought some head plugs from late model to put on the head where this hose should be going. Again the car is stock and it's a 5 speed. Sry for the long story jus want to get this issue resolved cause I know I'm losing HP and has mileage.
