Hey everybody i have been doing reading and trying to solve this problem for months but I am getting quite confused. I will layout my post as organized as possible.
The Symptoms
-Somewhat hard to start ( When i first crank it over it will start then immediately die(unless I give it gas). I try to start again and it takes a couple more cranks then the first time before it starts, after it starts it is REALLY shakey for about ten seconds or until I get on the gas)
-I believe the previous symptom might be related to my others
-At idle there is a random misfire
-That same random misfire occurs under light load/cruising speed and creates a jerk
-Usually never misfires under heavy load
- Right after accelerating I let off and sometimes hear a blurb blurb blurb and maybe even a backfire high up in the exhaust. FYI I do not have a muffler ( Best way I can describe it is a stock car decelerating
right after being on the gas hard)
-I notice on the highway (I drive the same stretch every day) that sometimes I will have more power going up that hill the other day/ visa versa. Or I think weird I didnt have to downshift to 4th yesterday to keep it at sixty going up the hill
Attempted repairs
-New distributor, cap, wires, rotors, plugs
-Checked timing
-All new fluids around
-AFM Checked
-TPS checked
-Throttle Body Cleaned/Intake Plenum
-I HAVE NO CURRENT CEL CODES
-BOUGHT VEHICLE AUGUST 2010
-CHECKED FOR STORED CODES MONTHS AGO, CODE 7? THE TPS CODE
So I adjusted the tps, which was new by the way, cleared the codes never came back
-This is just what i can remember
The Vehicle
-1987 4runner 292,000
-22re rebuild 15,000 (Never saw paperwork but it pulls hard....for a 22re)
Update
-Checked the Ignition Coil today
Spec for Primary .5-.7 . Spec for Sec. 11,000-15,000
My Primary was 1.7-2.0 and Secondary was 14,000
The Question
I'm hoping I found the solution! I was wondering if anyone could chime in and tell me if my coil could be causing these symptoms?? Is being 1.0 off on the Primary a big difference? Any other components I should still check out? I would love nay feedback or any other ideas!?
Thank You in Advance, I bow to you toyota techs
