Question about 1994 Jeep Wrangler
1994 4.0 jeep wrangler 100,000 miles
had new catalytic converter put in and all fuel injectors changed.
While driving it starts to stutter and backfires, I press on the gas pedal and has no power. I put it in gear and does not move. the engine light does not come on. what could be the problem?
when in idle mode it seems fine, once i put it in gear and start driving it that's when it happens
'till you do some in depth testing of all systems, I'd place equal weight on every possibility. Make sure you cover the basics like fuel filter etc before getting crazy with it though. Also check cap. rotor, coil and wires. Idle cylinder pressure is different than that encountered when driving. This additional pressure will cause ignition spark to seek a better easier ground,(not the spark plugs where it should be going) causing missing under load.After checking , if you haven't found anything, its time to begin testing fuel pump pressures, modules and controls.
