Ok so I've chased my tail to the point of dang near pulling my hair out. I've had this issue for quit some time, haven't drove the truck in a long time because I was frustrated, low on funds, and can't for the life of me figure out what the hell is going on.
When I start it, it has a lope like I have a big cam. The exhaust smells of fuel and stalls out when coming to a stop. I have to blip the throttle to keep it running.
The only CEL's are for Open Injector Circuit 3 & 6. I've check the wires for continuity, resistance, and voltage. All of which check out perfect. I've unplugged the injectors when running and can tell those cylinders drop out so I know they're firing. The truck fired up and ran beautifully when I put it back together. Idled perfect, drove perfect, and got good gas mileage. It is making a sucking noise from the throttle body that is fairly loud. I've check around the manifold, vacuum lines, and TB for a vacuum leak. I found one near the TB and fixed it. The idle did improve but barely. I'll list what has been done to the truck prior to these problems and what has been done since then to try to fix it.
Done 100 miles before the loping and stalling.
New rebuilt factory heads
1.7RR
Mopar M1
52mm TB
Shorty Headers
3in single exhaust
Done after the problems came about.
Compression check (cylinders are at 150 across the board.
New IAC
New MAP
New TPS
New coil
New Mopar performance PCM (to rule out my factory one)
New wires and plugs
New injectors
New distributor cap & rotor
New camshaft position sensor
New crankshaft position sensor
I'm desperately seeking guidance on what to do next? I miss my truck and want to be able to drive it so badly.
