I have a 1985 Pontiac Bonneville with the original Motor in it. It has the 5.0L 305 V8 with the original Rochester Quad-Jet Four Barrell. The motor just hit 100,000 miles. I am the second owner.
I have owned it for about 2 years. Motor has never been tampered with, either has the Carburator. All I did since I have gotten it is given it a tune up and put the hyper-tech chip in it about a year ago just for better gas milage. It's been driven daily back and fourth to work since I've bought it. But my work is about 25 miles away so everyday I got it over 60 mph. 6 months ago I quit driving it to work and had my wife start driving it daily to her work which is only 2 miles away there and back so the car hasn't seen 50 mph in the last 6 months. Now just last week it started popping from the carberator. It only does it when you goose it. Now I have talked to 6 different mechanics and 4 of them say its the timing and 2 of them say it needs a CAM job. Yesturday I went out and bought the Distributor Wrench and loosened the distributor a little bit, I turned it a tad to left aand still got popping, turned it to the right about an inch,still popping,another inch to the right still popping, and another inch to the right and still popping, so then I turned it back to the origianl position and re-tighting the distributor bolt. So I guess I ruled out the timing being the problem. Now what I need to know from you guys, does it need a "CAM JOB"????? Help Me cause I don't feel like dumping $500.00 right now.
