So going from stop till about 2500-3000rpm in first, it chugs like it's getting ready to stall, then when it hit 3000, boom! Gone like a snot rocket!
Any ideas? I got a p0144( I believe, havent checked in a while), but it's the evap code. Done the carbon canister, sensor, and gone as far as changing the spider injector. I'm starting to think that its the gasket around the pump. I changed the pump about a year ago, and it's been coming up for about 7 months.
Post the fuel trims for idle and for 3k rpm. There could be many factors, like IAC, MAF, leaking injectors.... Way too many to shoot accurately nor to give a sense tip.
Finally got in the blazer today. And remembered to get the pics. Idle Idle Idle Idle Idle
all above are from idle... 3000rpm 3000rpm 3000rpm 3000rpm 3000rpm
now these were all taken while engine light has been off... it's been off for a while now. It comes and goes with an evap code. I cant find anything, replaced the carbon box and sensor. Got a new gas cap. Checked the oring on the tank. I'm at a lost. My gas mileage is crap again. When I replaced the o2 sensor and cat, my mileage based back up to 425km/tank. City driving. Now its back down to 350-385km/tank.
