Hey there Im new on here and not a mechanic, but I've seem so solve my 99 Isuzu Rodeo stall and idle problems( so far). First off, after months of my 99 Rodeo stalling while driving and cutting off I was fed up. I noticed the RPM drops when the car stalls. ( When it stalls, it doesnt even rev up, fells like Im in a dead car just press the gas pedal, then it picks up speed for a second the BOOM, stalls again I did the carb spray on intake manifold test-no vaccum leaks, I cleaned the pcv valve, cleaned the throttle, new air filter with no results. Next, I cleaned the IAC (idle air control) with carb cleaner and it ran fine for about a day. Last I replace the Fuel Pressure Regulator and then viola!!! its running fine for about 2 weeks. now. It took me about a day to replace it hence im not a mechanic and its located on the fuel at the drivers side firewall. I had to literally remove the whole whole fuel rail( for the 99+ models) which was a real bytch taking off, but easier putting back on. Sorry for the paragraph but I feel I had to tell someone of my triumph lol. I hope this helps.

#74 of 101 Does a bad temperature switch affect fuel injection on a 1994 Isuzu Rodeo?

Does/will a bad temperature switch affect fuel injection on 1994 Isuzu Rodeo 3.2L? There appears to be 2, one larger sending unit with a 2 wire connection (plug) and a smaller one with a single wire (blade type) connection. I believe the smaller one controls the temp gage at the dash, which has not been working. I found the tang (connection blade) broken off of the sensor switch. The vehicle has been bogging down and blowing black smoke intermittently after the engine is warm and I am wondering if the temp switch may be the problem. Any help is greatly appreciated, thanks.

So my '95 Rodeo is having starting issues. I believe it has to do something with the fuel pump.
Right now I can start it and it runs fine, but in the past, I have had it die on me while I was driving on the highway. I have replaced the fuel pump with another one from a '96 or a '97 rodeo and when i turn the key to the start position or to the position where it doesn't start the car but turns everything on, the check engine light comes on and I can hear the fuel pump pumping. Once i start it up, the check engine light turns off and it runs fine.
But every so often, when i turn the key to the on position, the fuel pump wont pump. And it will stay like that for a while. It is quite unreliable and I would like to find out more. I was thinking of just rewiring the fuel pump cause it might be a bad connection but I don't want to have to pull off the fuel tank for the third time.
Please help. Thanks.

derving2010: I've had all of your problems with my 1999 Rodeo and can not find a solution. I was wondering if yours is still doing good after replacing the fuel pressure regulator?

I changed the pcv valve (2.99) and more importantly, the rubber grommet it sits in..buy seperately.. the rubber piece was rotted and not making a good seal. My car has been idling even and not stalling for several days so far so good.. cost me 5 bucks. I am crossing my fingers...
