    coolant temp reading-PL or gauge?

    I have it the other way around. My VDO gauge is showing like 185° sitting idle with the AC on and the scanmaster is showing 215°+. I have a cold case aluminum rad with dual fans and a box in kit. I changed the gauge sensor at one time but I think the ECM one is original. Do they fail over...

    1987 GN won't rev past 4K RPM.

    The previous owner had the car sitting for a while, he decided to get it running so he drained the gas tank, put fresh gas and tried to start it. It ran like crap so he replaced all the fuel injectors with accell 30lb injectors and put new plugs and a coil on. It ran better but had a...

    1987 GN won't rev past 4K RPM.

    I'm still getting the hang of the scanmaster readout. I don't really push the car until I get this sorted. I ordered the comp 980-12 springs, and just ordered the walboro pump and Hotwire kit from Gbodyparts.com. I'm more then willing to invest into this car to maintain it and keep it...

    AVC VSS sensor.

    On eBay. Lol. It was $40 and supposedly tested and guaranteed to work. I plan on installing it this weekend and hope for the best.

    Thanks, I reached out them and they have the sensor, I'm going to replace the buffer first since I already have a replacement sent to me. Appreciate the info.

    1987 GN won't rev past 4K RPM.

    So recently I picked up a 87 GN and I had a issue where it would bog out above 5psi of boost. Well a new fuel filter solved that issue. Now it will build almost 15psi of boost but The engine goes flat at 4K rpm. No timing retard on the scanmaster and no popping or any abnormal noises, just...

    AVC VSS sensor.

    My car came with the AVC GNX style gauge cluster and the VSS was never installed with the gauge swap. I keep getting the check engine light code 24 for the VSS and I'll like to get this repaired. Would anyone happen to have one for sale or be able to point me in the right direction where to...

    Drivability issues

    The fuse took me having to use a needle nose plier to remove. It was very tight. I actually removed all the grounds and cleaned them up and now I can check power at my fuses all the time. Just my scanmaster communication light turns off when the brake lights come on. I'm going to use a...

    Drivability issues

    You are co You are correct, lbs per hours, not psi. They are accell 150630 fuel injectors. The previous owner bought them from Summit racing. I pulled the coil up and the wires to the module are correct according to a picture I found online. Now here's another issue that's probably my...

    Drivability issues

    I would agree with you that if I went from stock 29psi to 42psi injectors that the system needs to be modified and I'll need a chip. I went from the stock 29psi to 30psi which is hardly any difference at all. These injectors are considered stock replacements, if anything, the tired old...

    Drivability issues

    Thanks for the info. The theme for this car is to keep it a stock original car. I have other cars that I spent plenty on performance modifications, this car is special to me so I'm just looking to keep it as original as possible. Just getting it running right is top priority! The fuel...

    Drivability issues

    Thanks for the information. It's a stock chip in a replaced ECM. I'm not sure when it was replaced, I just noticed the sticker on it was newer. I did notice on the scanmaster when it was working that idle TPS voltage was showing 4.8, I'm not sure how accurate that is since its been showing...

    Drivability issues

    I just recently picked up a one owner 87 GN and I been having a issue with it. The previous owner said the car was sitting for a while so he got it running by installing new plugs, wires and a new coil. Once it started, it was running rough so he installed all new 30psi accell fuel injectors...
