![]() I have a bad habit of projecting my P/M program onto every "help, having issues" thread I answer so I leave a lot of stuff out of my responses because those things are parts I consider 'consumables' and get r&r'ed every yr on my Z. My bad! ![]() ![]() Tom

Tom, Dominic and Yun,
Hey Guys, hate to admit it but when Tom mentioned the MAP hose it struck a nerve. When I bought the car and was battling high idle I replaced all the vacuum hoses and in stalled clamps. Yes, the MAP hose was replaced with rubber hose because the rubber fittings on the ends of the hard plastic tube were deterioated and falling off. So I did the exactly the wrong thing as confirmed by Yun. I ordered a new correct hose from White Racing Products (not inexpensive). Can't wait to get that hose on and if it's not the final answer will proceed next to fuel starvation. I did change the fuel filter a couple years ago. With your guys help I will have the beast running like it should. Thanks, Dennis |

Hi Tom, Dominic and Yun,
You guys are awsome. With all the warm weather in the Buffalo area I couldn't wait until I got back from Florida to install the new MAP pipe. Guess what, it was the dreaded MAP vaccum hose that I incorrectly installed just as Yun said and Tom suspected. Wow, the Z is now a pleasure to drive without the threat of an idle stall and accelerates smoothly in any gear with no bucking. I will also check out the fuel pumps and codes when I get back home. I can't thank you guys enough. Stay tuned you are now my go to guys for any future problems. Dennis |
