  • WTF is going on....

    I've got a 91 gtst with just exhaust and a cone, I've had it for just over a year and its always had a little bit of a hesitation issue right as I build any boost but it would always clear up when it warmed up. I just got back from Edmonton the other day and its gotten worse.... alot worse.... it has a hell of a time starting now and bucks like crazy in low rpm, feels like it has half the power, and when I'm just cruising through town it will feel like it drops to a 3 cylinder and I have to build boost just to maintain 60 kph. I don't know if its my coilpacks, tps, cas or what but my cars not even drivable really and too top it off I just did a compression test (cold) and the number I got were a little disappointing, (1)145, (2)120, (3)130, (4)140, (5)130, (6)120. Any ideas or suggestions would greatly be appriciated Thanks guys

      Best replacement would be the Walbro?

        I would say Maf issue, and the comp numbers aren't super low considering its cold, but they do vary quite a bit which is worrisome.

        Do a leak down, and try a new maf or ignitor. Good luck

          This is definitely plausible too!

              I got a Walbro GSS341 that I ended up not needing if you want. The pigtail's missing but its new and the equivalent to a BNR32 factory pump.

              Pm me if you need a pump for cheap. Could be that or the MAF, cleaning and re-soldering the MAF is free and easy, try that first, there is a tutorial on here on how to do that.

                having a bad maf shouldnt give it a hard to start one. one gts i fixed had a bad maf and would start fine but if would run like ****. mine when it had a bad fuel pump it was very hard to start and had no power. op pm me if you want i know someone selling a walbro 255 for like 80 bucks

                    Well I re soldered/cleaned my MAF, adjusted my tps, and replaced my IACV with a "refurbished" one and everything seems to be alot better! Let hope it lasts haha
