FIrst post here. I discovered Paul’s channels some time ago and have learned quite a bit from the book and videos. I really appreciate all the effort Paul puts into his quality content.
‘96 Toyota Tacoma 3.4L 5 speed, 210K
I was hoping to get some advice on some trouble I’m having w/ my truck. If I try to accelerate at more than a conservative rate it will hesitate, shudder. If I back off on the gas or downshift, it will accelerate.
I”m looking for direction. I don’t what to just be a parts swapper here. Just because it was due anyway, I did put in a new set of plugs, fuel filter and cleaned the MAF.
I have all the basic tools. My only ‘scanner’ is the Torque app and a OBD2 bluetooth dongle.
My timing belt is due to be replaced (it probably has 120K on it). Gas mileage has always been in the 21-23 range and is unchanged. Aside from the acceleration issue, it runs fine. No CEL or codes.
At idle, LT fuel trim is +3%, ST bounces around +/-3%. Driving straight and level LT +2.5 ST +/-4. During an accel, LT +2-+6, ST +4/-3.
Any thought on direction and checks checks I can make? How could I check for plugged injectors or a timing belt issue? How would an EGR issue present itself?
