The car is an 84 McLaren Capri style with the 302 cfi setup. 55.000 miles, not rolled over.
If anyone can lend some advice about a power drop-off under certain conditions, that would be helpful.
If tank is full, I have all the power I want.
Below 3/4 tank, while on an incline, power seems to be intermittent, as the rpm climbs conditions worsen. improve a little on flat land and goes down hill a little better. We're talking highway speeds here. Hardly occurs at around town speeds.
My first thought is the fuel pump. (not another one...), just did one on my 87 McLaren.
Then I read that the CFI cars have a return pump also, and the mechanic at work is confusing me talking about vacuum lines and such.
I can tell that this is something that I will have to educate myself about. I don't even know that I'm on the right track.
Ignition problems enter into my mind as well.
Anyone have any ideas or experience with these symptoms. I really want to analyze all the possibilities and perform whatever tests I can to determine the problem before I spend any money unnecessarily.
I have been reading on the MAP sensor and related problems, but in my mind, an electrical component gone bad, does not explain why the problem goes away when I top off the petrol. I'm thinking secondary fuel pump, but I'm looking for a difinetive answer before I spend. And that's never how it happens unless your well informed technically.
