I have a 1996 dodge dakota 2wd took out the 5.2 and put a 5.9 in headers no cats no 02 sencers and my problem is when i start it cold idle is good but if i take it to 2,000rpm it will bog down then...


Without input from the O2's, the engine goes into fail-safe mode and runs in a full rich fuel trim. When the engine is cold the spark plugs are being "loaded up" with unburnt fuel, and engine stumbles. Hope this helps.

Cranks and idles good but will not accellerate no codes on engine fuel pump pressure 38to41 new fuel regulator , cat conv punched out 98 Suzuki Esteem


1998



1.6L or the 1.8L

good pressure. no melted cat.

so what engine,, (but both are MAF based systems)soooooo

low power, all the time. lits call it bogs. (3letters)

elaborate that, when does power end.

hot , cold both engine temp?

only tip-in BOG... you move foot fast , it bogs then catches up.?

or you TIP-in and its bog city all the way to WOT. ( wide open throttle)



when was the last time car was DD, a daily driver.

last week ,month or decade? key question.

bad fuel of over 6months old fuel?



here are the tests.

1: all fuses good. (always for ever and ever)

2: key on,

3: the dash lights up , oil, charge, and CEL, is the CEL on, it must be.

4: start car, CEL goes out , does it, stay out running???????

5: bogs, hot ,or cold engine block?

6: no codes, does that mean an OBD2 scan tool shows no DTCs stored, and no pendings, and all monitors complete, no it wont

with the CAT gutted,, it will show P0420x for ever. bad dead cat.



what does no code mean.

here is a oBD2 1996 scan of the G16b ENGINE,

the J18 engine would do same......

http://www.fixkick.com/ECU/Authority/A_Full_OBD2_scan.html



see the tests. here.



bogging with either engine, hard lasting hot bogging, is:

in no order... fate is random , in many cases...

1: low fuel pressure, (not you) stated for full correct.

2: clogged injectors.

3: bad fuel.

4: weak maf, ECU cant tell weak , only dead. or just a dirty maf. ask.!



one way to prove a WEAK maf, is to unplug it

the ECU then see that and creates a virtual simulated MAF.

it will not have full power, but will have lots.

it will run in suzuki limphome mode, with retarded timing, and low power and limted RPM.

it will suck fuel.

i never do it because i have the outputs logged. i use a voltmeter

1994 Jeep Cherokee is bogging down and getting hot!


ok if the timing chain was bad it would not run. bogging down is from increased resistance from something. since you have overheating i would guess the water pump broke when you heard the sound. ther is a belt around it and that would cause this. since it idles fine i would wait till it is cold and open the radiator then run the engine and see if you see water moving in the radiator. if nothing after 10 min then i would suspect the water pump. watch that you don't overheat the engine doing this. that would cause other problems that could be more expensive to fix good luck

98 Corolla stalls or stumbles when cold


It sounds like you may have picked up some small debris from the bottom of the gas tank when you ran it empty. You may need to run a fuel/injector cleaning solution through the next tank of gas to clear the debris and consider changing your fuel filter too. Sea Foam is a great fuel additive and I recomment trying it full strength. Hope this helps!

Starting Problem


Look on the distributor. There is a module on it that, when too hot, will cause miss/stall/no re-start situations.
