So I got my car back from the local Porsche shop and installed a rebuilt MPS from Bowlsby but the car is still not running right. Flat spots and intermittent dead fire misses. She starts right up, idles well and drives ok but when you get on it it has intermittent flat spots and when shes just cruising it misses once and a while. Seems like the advance is not ramping up like it should. Also, the mechanic left a vacuum line off the distributor. The line from the inboard connection on the pot is hooked up but the outside one is off. I understand that one of these is advance and one is retard.
Just need a list of crap to check (IMG:style_emoticons/default/biggrin.gif) |

Here's a repost of my comments in my build thread:
So I had the local independant Porsche shop looking at my car over the last six weeks or so. They did allot of good work making the engine run properly, but they never got it right. The car would buck at various RMP. Mechanic said that the fuel pump might be to blame so I say, "replace the fuel pump." He says, "we want to make sure that's the problem." I tell him if you charge me $135 an hour to figure out that it's the issue then you might as well buy a new pump for $130 and install it. Then I'll at least have a new pump to show for it. I also tell the guy that it's probably the TPS making it buck. I get a call a few days later that my car's "ready and running great". No fuel pump and no TPS installed. I pick up the car and guess what? It's still bucking and running like crap.... sheeplove.gif Soooo..... Last night I installed a new fuel pump. Car runs allot smother but still bucks Soooo..... This morning I installed a TPS that Rich sent me last week. You guessed it, that fucher's running like a fresh spun top. Why won't mechanics listen to people? I mean I obviously know a little bit about my car, I built the thing from scratch right? People..... headbang.gif |
