Okay, well once again I had to take my zcar to work instead of the Volvo. Recently I've been plagued by an intermittent problem, where it doesn't want to rev, or have any power whatsoever. When it first started, I was pulling away from a stop light, after I had been driving fine for over 30 miles and all of a sudden it would not rev past around 1500 or 2000rpm. It seemed like it would cut the fuel passed a certain rpm. I assume because I don't have a tach. So I left it for a while, had lunch across the street, then started it again and it was fine. I assumed it was the mass air flow meter, since the Nissan meters do the same thing when they go bad. Probably a bad decision, but I decided to anyway.
It had been running fine for the last two nights. I drove atleast 50 miles each day with no problems. I thought I had fixed it, but it reared its ugly head again tonight.
So far I've replaced, in the last two months: NGK plugs, new bosch wires, cap & rotor, new ignition coil, fuel press regulator, new gaskets for the intake & throttle body, new stanby fuel pump, main fuel pump, fuel relay, fuel filter, and now a rebuilt air flow meter. The harness shows no signs of damage, not near the firewall or the alternator. All of the vacuum hoses were replaced when I did the intake gaskets. I haven't checked the timing, other than when it was running fine. The timing was set at 12, and the ignition advance computer thing (mounted near the wash. res.) appeared to be working, as the timing would slightly advance when revved. The 25 amp blade fuse, by the battery, is also in fine shape as well.
This post is getting really long, but I could really use some advice on where to go from here. I'm really pissed at my Volvo...it has not been very reliable at all. And it seems the more money and work that I do, the more that things break. Please help...before I decide to give up and sell.
Thanks
Jack
