After replacing my manifolds and getting everything back on the engine the car started running like crap....
So here is my first issue....I think this one may be the cause of everything else. When I try to start the car sometimes the fuel pump seems like it isn't working. Well one day I got an idea to try and jump the pump to get some fuel into the lines (I have a paxton in-line and no in tank fuel pump). After I connected the wire everything was working fine...the car cranked and was getting fuel. I cut it off and it'll usually crank but sometimes I have to go and jump it again....any ideas?
Second issue...everything was running fine b4 I took everything off....but after I put everything back on it was rough. I also changed my dizzy to one of those msd pieces. When I cranked it my vacuum was around 10-12 at idle and the idle sounded like it was missing on half the cylinders. I haven't set my timing with a light yet..but I did twist the dizzy some so that it would be advanced. Could an out of time engine cause the vacuum to be that bad..it used to be around 17.....oh yeah, the idle is also at around 800 where it used to be at 1100 or so
Oh yeah, when I took the car to drive around it seemed like after I let the clutch out the car would jerk around alot...to the point to where it would seem like I didn't know how to drive stick. And also when I would accelerate the car would go up in steps and wouldn't get much past 2500 rpm before it'd start bogging now. Again...could the timing be the culprit you think? I knew it could cause problems...but not this bad.
It could also be my computer...I think my tweecer went out on me and for some reason there is a gt computer in my cobra.....my cobra with 42 lb injectors and a 90 mm maf off a lightning. So perhaps my computer is going off the 19 lb/hr slope and dumping wayyy too much fuel in.
When I rev the car in idle it will kinda jerk its way up to 2500 or so and then will start popping and what not. Also, when I first crank it up the car runs excellently...until it idles down. When it's first cranked my vacuum is around 16 and when I rev it the car revs evenly..instead of in steps. Then it will bring its idle down and sound like its running on 4 cylinders.
So....to those of you that have made it through my post...or rather my novel.....what does this sound like to you? Too much fuel...or maybe the timing being a little off could cause all these problems. Like I said, I installed it at tdc and turned the rotor clockwise maybe an inch...I also tried it after turning it about a half inch...
Thank you for your time and any replies
