OK well I had been worried I would need a new carb on my '88 Brougham. The previous owner told me the last guy charged him $600+ to rebuild his carb. I asked him why a new carb doesn't cost that much and he said the re-builder said "Well if I screw up I need to be able to cover buying a new carb". See that to me says don't let him rebuild it but I digress.
So anyway after addressing the TC Lock-Up solenoid, hammering a straight pipe through the cat timing set about perfect, new fuel pump and fuel filter. The engine was running kind of eh. Felt like it might be too rich. Oh it is a 307 with the E4MV Q-Jet on it. It would bog down on hills, have to feather the gas. So I went to go find the mixture screw (couldn't even with an exploded diagram but it was night so oh well) and while looking I noticed a ripped vacuum line. I had already fixed other Vacuum lines on this car.
Some history to digress again. The previous owner told me as well that his car had an intake manifold leak (as a shop told him) and he also had a leak in some booster fuel reservoir thing (that neither me or a professional mechanic friend have ever heard of). Those items were why the car had a bobble at idle.
So anyway this vacuum line connects direct into the intake manifold half-way between the carb and the thermostat housing. It was ripped right at the nipple. Took it off, cut the end off, presto, everything is well. Amazing what a difference the plethora a vacuum lines make on a car. I almost feel like the engineer for the '88 was subconsciously craving a big plate of spaghetti and that became his inspiration for the layout!!!
On a side note to all this, I have a question. Going over the service records the previous owner went through and now going over the car myself I am just shocked at the bad information and bad work the previous mechanics did on this car. Part of me debates telling the old owner out of courtesy. I am just wondering if the profession is going that downhill or there really are so few mechanics who work on Caddy's that they are lost for some reason. It just shocks me.
I mean I found this line because I happened upon it by accident and said "well that ain't right" but I would think a professional mechanic would think to check such things.
