Yeah the title says it all.
1992 5-spd 4x4 sport. 117,000 miles
Runs excellent once I get past 1400. It has a homemade high-flow intake (completely leak proof) and flow master exhaust with high flow cat connected to the y-pipe by a reducer made by me (also leak proof). It's got a somewhat erratic, although smooth, idle (much like a mild performance cam). The problem is much more noticable when the engine is cold...
I have:
1) Changed spark plugs
2) Tested wires to be good (replaced 9 months ago)
3) Run SeaFoam through the intake
4) Cleaned MAF
5) Scanned computer and got nothing on both KOEO and KOER tests.
The secondary resistance on my ignition coil is a bit out of range, they measure about 14,000 ohms while the Hayne's manual specifies 5,000-11,000 ohms. Could this be it?
Could it be fuel related?
O2 sensor (even though the comp doesn't say the O2S reading is out of range)?
Please post any ideas
