Question about 1994 Pontiac Bonneville

2 Answers

My 1994 Bonneville is hard starting and the gas pedal must be pumped continually to keep it running. the rpm's will drop or raise 1000 rpm or just shut off. I cannot drive as is. I have cleaned the injectors and replaced the fuel filter.

It could be a cracked coil pack and the ignation pack under the 3 of these (change everything its cheap enough)

http://www.amazon.com/MSD-Ignition-8224-Blaster-Replacement/dp/B0006306XM/ref=sr_1_14?ie=UTF8&s=automotive&qid=1248472003&sr=1-14

ours are balck and round. tthe pack under it is a rectangle. does the car keep going when you feather the gas pedal? like its missing big time? in the rain or a dry day? changed the 3 coils and the pack myself with cheap *** parts from a supply house for less than $50. my 92 sse just passed inspection with 180K today, freaking LOVE that car! did the struts and shocks are next.

you may have a bonne and the coils may be one large piece that looks like three individuals. get what you have now! always! they gave me an O ring for my thermostat instead of the gasket, after everythign was back together it was shooting out coolant. i waent and got a gaskets, zero probs.

they have no numbers on the new coils so i hit them with some white out and wrote the cooresponding number on it with a sharpie as i replaced them one by one.

good luck

Try cleaning off the two wires that stretch across the inside of the mass air flow sensor, using a q-tip and carb cleaner (carefully). If that does not help, check the map sensor. Either one can cause changes in fuel mixture.

My 94 nissan sentra doesn't run smooth over 3000 rpm or if you mash the gas pedal


I have a 2000 Chevy Tahoe that did the same thing. I changed the oil pump, new oil, and head gasket. It now has power and doesn't fall on its face when I step into the throttle hard. Hope this helps.

Rpm does not drop below 1000


No,only on carburated engines it,idles down to the set point,on yours,it's fuel injected,pushing gas pedal won't kick idle down,should go down after a certain amount of time,does it automatically,If you start and drive a 5 mile ride and stop at a stop sign,it should idle at it's set point if there's no engine problems,which may be.5 to .7 on your tac.When you normally first start,it will idle between 1000 to 1200 rpm's,don't push on gas,let idle say 15 seconds,put in drive and go.

Try checking the codes. You can do this at part stores like auto zone for free. It might be the maf sensor or if it says lean o2 sensor than it's the fuel filter.

Fuel pressure intermittently drops causing sputter and die.


check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump
