Hi this is jacob, im 17 and this my first time posting so inform if im doing it wrong!
Okay i have a 1999 tacoma extended cab sr5 3.4l manual,4x4 with 183000 miles. I love it, but about 9 months ago it started jurking or hesitating while cruising! So i replaced the ingnition control module...didn't help! Then i cleaned the throttle body and maf sensor, didnt help. But it was fairly dirty from that big hose that comes in to the back of the intake tube!( a valve cover vent i think) so i replaced the fuel filter, spark plugs and wires...didn't help! There is no engine light on! I got me a cheap obd2 reader and it said the evap system code was thrown! So i checked the valve on the charcoal canister. It works! The charcoal canister looks new! Got new gas caps, both vented and sealed. Neither one helped! It jurks the worst at around 55mph and it never jurks at wot! Seems to get worse under a quarter tank! I have no way of getting a smoke tester! I Always run 91 octane! Should replace the fuel pump? The fuel line has wet spot on it were it runs though a bracket after the fuel filter! It idles at about 1500rpms and lopes or... it idles up and then down and is never consistent but it has never died! I cant adjust it down, ive tried!No power loss that i can tell! Ive checked vacum lines! Is it just time to replace the timing belt again? I have no clue wen it was done last cause im the second owner! Any help will be appreciated!
Hope you can make sense of that!
Thanks,
Jake
