Having problems with your 1993 Jeep Grand Cherokee ?

1993 jeep wrangler 4.0. Jeep stalls when accelerator is slightly engaged. sometimes hard to start after this. sometimes starts right up. already replaced crank position sensor. What else could be wrong? Auto shop at school cleaned plugs and dumped fuel injector cleaner in tank. Fuel pressure on gage reads 30 psi then increases to about 40 psi when vacuum line is removed from fuel pressure regulator. Could the problem be the TPS? or cam sensor?

Answers :

The fuel pressure you listed is to low,
The regulator should keep the pressure down to at least 45psi,removing the vacuum from the regulator it should spike to at least 55-60.
Did it start and run better with the hose off?
replace the fuel filter first,then check the pressure again.
