2005 pontiac vibe gas mileage8/15/2023 We like our Vibe, but we would like to get better gas mileage. If we have ABS, do we need w/Active brake control? There’s only one choice for the Matrix there: STANDARD MOTOR PRODUCTS Part # EM11375 Reman, which oddly enough is my exact same 89661-02K41, says w/o Traction control.Ĭan someone advise me on what to do? Has anyone replaced ECM like mine that was not covered in the recall? And where do I complain maybe there should be an extended recall to cover mine, too. ACDELCO Part # 19205364 MODULE,Powertrain Control w/ACTIVE BRAKE CONTROL(JL4) or 4-SPD AUTO TRANS(MU4) Base Model. Not sure which ACDelco model to pick there-Vibe is AT, FWD, base w ABS. Does a dealer have to do it, or can I do it myself? My husband thought of RockAuto as a place that might carry new ECMs. I’ve also read that swap outs may need programming. ![]() The 2005 Pontiac Vibe has 3 model options: Automatic 4-spd 4-cyl, 1.8 L, Manual 5-spd 4-cyl, 1.8 L and Manual 6-spd 4-cyl, 1.8 L. I’m wary of a used one (from eBay) unless I could get one from an owner who swears he got at least 30 mpg. Home Pontiac Vibe 2005 Pontiac Vibe MPG and Fuel Economy 2005 Pontiac Vibe MPG and Fuel Economy On this page, you will find a complete guide to the miles per gallon and fuel efficiency data for the 2005 Pontiac Vibe. Is there any way I can hack the existing computer to fix it to get better mpg? I’ve looked online for used and new replacement ECMs. I still think the lousy mpg is due to some defect in the computer. Hard to read those small numbers, but with a mirror, I think mine is 8746, so the chart said it was “good” and not eligible for the replacement under the recall. ![]() We had the tires rotated so the better ones are on the front. Fuel economy is a strong selling point for the Vibe, as it gets better highway mileage than. Since they were more worn than the back, I imagine the previous owner had had the same problem for some time. Its compact design delivers good fuel economy and roomy cargo space. The Vibe was squealing the front tires when we would drive off from a stop. I searched for reasons for the poor mpg and found a thread about “jack rabbit starts and poor mpg of 19-21” and think mine may have an ECM computer problem. Plenty of power and no CEL, so we don’t think O2 sensors or catalytic converter would be the cause. Bought new spark plugs and PCV valve but haven’t put them in yet. We replaced air filter, put Techron fuel additive in two times, cleaned MAF sensor, using the excellent instructions we found on this forum. ![]() However, gas mileage is poor, less-than-expected 23 mpg, no matter city or highway, no matter gentle or more aggressive driving. Around 95,000 miles now and seems to run good. I bought a used 2006 Vibe base from a GM dealer a few months ago.
