Grand prix sputtering


First off, is a check engine lite on,if so do you know the codes?It does have a cam sensor,the cam sensor malfunction gives a code reading,in general fuel probs do not give a code this is done bymanually checking fuel press ect....the module does give specific codes as well...I have seen a cam sensor give the prob. you list, BUT TEST BEFORE YOU BUY,you can get your own codes from the a.l.d.l connector,under dash...take a coated jumper wire and push one end into the g .circuit ,the other into the b terminal and watch the lite flashig in the dash,,ie, 2 flashes...pause then 4 flashes is an example....wilf

You need to get the trouble codes out of the computer first. Take it to your local autoparts store and they can hook up a scan tool and retreive codes this give you a general area start looking for the problem.

1992 Chevy S10 2.5L-4 cylinder. just started today outta no were. it idles really rough and pops then when i step on the gas it sputters and pops also smokes a little. help please..


My 1990 S10 pick-up had a similar problem too. It would start up fine (while the engine was cold) then once the engine warmed up it would idle very rough, sputter, and even stall out. My grandpa and I found what was wrong finally. The fuel distributor had been cracked, so when the engine warmed up it would miss (giving either too much or not enough fuel). So I recommend that you check that. Hope this helps.

Truck has 305 motor fuel injected idles fine when in drive barely exelerating it spits and sputers and sometimes dies but when i get into the exelerator a litle bit it doesnt do it


if it is an HEI distributor remove the cap and rotor there is a module under the rotor take out the two quarter inch screws and unplug it take it to your local parts store and have it checked that is the module that controls the injection rate,if it is not HEI then do an injector cleaning,also try running a tank full of high octane gas through it the injectors sound like they have gunk built up in them,hope this gives you a place to start
