    5.0 rebuild

    It really depends on what you have done to it. I would budget $2500. Are you having any troubles with the engine?? I would check the oil pressure with a mechanical guage as well as do a leak down test before doing anything with the motor because................. if it ain't...

    89 5.0 GT Convertible 25th anniversary

    Not with that many miles on it for a stock GT!! There are too many of them around. Sounds like it might be a nice car though. To have value as a collectors car, it would have to be all original and have very low mileage, preferbly less than 10,000 miles.

    Can't get TPS voltage above .15 volts - part 2

    My gut feeling is that it is in the injector harness somewhere since it is not the one that I took off the car. Friend of mine says he has an extra known good injector harness. I am going to swap that one in and see what happens.

    Can't get TPS voltage above .15 volts - part 2

    Diagram 1 is correct with the exception that VREF +/- 5v and TP sig +/- .17v occurs both with SIGRTN connected and cut. In looking at the diagram, it makes no sense, but if you note all of my last voltage readings were with SIGRTN cut. Diagram 2 is 100% correct. Looks like a bad TPS...

    Can't get TPS voltage above .15 volts - part 2

    Will try that , Joel HOTCOBRA03 The injector harness ground is at the firewall and is good. With a DVM pos lead on pos post and key off I get 11.96 volts at neg batt post and 11.96 volts at firewall ground point. Assuming that the original TPS sensor wasnt really bad, I have had...

    Can't get TPS voltage above .15 volts - part 2

    Update DVM batteries are good. Not sure what you mean by check leads for continuity. Fired it up and took it for a 15 min ride. It now has a nasty surging idle. In fact, until it warms up, it wont idle. When I took it out for a ride, everytime I came to a stop sign, it died. Pulled...

    has anyone ever heard of staab agency?

    It is a legit business but it is mostly for trailers. Alot of truckers do it to avoid the taxes on trailers. There is no inspection of trailers in ME. I doubt that you could do it for a motor vehicle though. Cops tend to ask all kinds of questions when you have a DL from on state and a...

    Fuel Pump and MAF questions

    If you are going blown, you really need to think out your air/fuel delivery combination. You do not want to run a blown motor lean. Make sure that your air/fuel ratio is good and you have a safe tune. Injector sizing will depend on amt of HP you will be making. How much HP are you...
