So after being a bad owner and not starting my car over the winter I got her started back in April and took the car to my mechanic. The car started but I could not hit the gas pedal without her stalling. I wanted a few upgrades and had him install a weiland 4bbl intake manifold and edelbrock 600cfm 4bbl carb. He also ended up doing a tune up as well. I replaced the points with an accel conversion kits a few years back for some background info.
Well I first get the car back a few weeks ago and it starts right up and idles nice. It rode nice at average speed and very little throttle but when I hit the gas it just wasn't very responsive and didn't feel quite right. It is a 383 by the way. The following week I drive it out on the highway while out getting estimates on interior work. That morning it didn't fire right up. As I drove she started to hiccup and backfire, like a rollercoaster going up its first hill and slipping back a little. I ended up driving a good 25 miles with the car like this, sometimes running nice a smooth and then out of the blue having the hiccups. When I finally get her back to the mechanic we notice an oil leak from the timing chain cover. He changes the gasket and while in there I tell him to check the timing chain which he changes. The car has 140K miles so I figure its as good as time as any to change.
Well I get the car back Saturday and she fires right up, sounds really nice. He says that the slack in the timing chain was causing the hiccups and all is good to go now. After driving her to get some gas she feels much more responsive then the first time and I think all is good so I take her for running my errands for the day. She drives nicely as I go to pick up food for the dogs about 20 miles away. When I come out of the store after about 10 minutes she wouldn't start. She's just turning over and over without any hint of starting. Not really knowing about how to check on items on my own I figure I will walk down to the store and get some carb spray, maybe she just needs a little kick. When I come back after another 10 minutes I try to start her first before using the spray. Well she starts, but not really fired up. It was more like I released the key and she started, but she started. I figure I will just take her back to the mechanic. I thought I would make one more stop at the bank first. Backing up into a parking lot she stalls and won't start again. I figure she just needs to cool down, so I get some lunch. I come back out and she starts, but in the same manner as before. I get her on the parkway and she is driving nicely but I am not pushing her at the same time either.
After about 25 minutes on the parkway, just as I am getting to my exit I feel her starting to lose power and acceleration and starting to hiccup. As i get off at my exit she stalls. thinking that all she needs to do is cool down again before she starts I wait. I try starting her after 20 minutes and she almost kicks, but then there is a gunshot of a backfire from I think the carb. another 20 minute wait and no sign of firing up. Fortunately a well doing mechanic stops by and tries to get her started with me. We check spark, gas flow, ect and all the components seem in place that she should start, but all she does is turnover. So a tow truck ride to the mechanic and now I am waiting on his findings. I told him this morning about what I have read on the website here regarding the sputtering and the intake manifold issue that was in a recent thread but he kind of blew me off on that thinking it wouldn't have idled or ran nicely in the first place if that was the problem. So, who wants to try and diagnose the issue? I will bring up any suggestions with him in conversation. Remember there are no points in the distributor if that makes any difference.
