Your problem is most likely a sensor problem. Did you get a check engine light? It could also be a fuel pump. These vehicles are verry sensitive to even slightly low fuel pressure. Once the pump starts to get tired they just start running crappy followed by stalling and hard starting. Id start testing cheap stuff first. Like the O2 sensor. If it has been a while or never changed then it needs changed. Should be changed every other year or so to keep it working in tip top shape. cheap O2 sensors may have to be replaced more often like once every year. Next I would look at the MAF sensor. These often get a bit dirty inside and affects the ability for it to detect the proper amount of air. Clean it with a MAF safe cleaner and it just might do the trick.

2001 Chevy venture intermittently running rough.


Check air filter. Check for any vacuum leaks. Check condition of plug wires. Were new plugs pre-gapped? If not, make sure the spark gap is correct for your vehicle.

1990 chevy silverado 1500 wont run


Code 12 means you are in test mode, code 34 is a problem with the map sensor, and code 35 is a problem with the idle control valve.
But those two codes could show up if you disconnect those sensors or if the engine is having other problems.
In situations where the engine stalls, it is very easy to overlook something or assume a component is working.
Treat it like a no start. Pull a plug wire and watch the spark as the engine dies. Use carb cleaner or starting fluid to boost fuel supply.
You'll have to figure out if it is loosing spark or fuel to proceed.
Things like the coil, the stator in the bottom of the dist, or a relay can be the cause. Even low fuel pressure.

1994 Chevy Suburban K1500 5.7L v8 157 thousand miles.. replacing timing chain on the vehicle and after replacement truck ran steady at 1k RPMs. During idle in park the following day the truck died, re


First you need to retrace your steps...before you changed the timing chain and gears did It run ok ? what was initial problem, next put a fuel pressure gauge on your fuel line and cycle your key on to run pos, dont have to try start, just run and see if you have fuel press during the 3 sec or so pump cycles, should be around i think 35-45 roughly for tbi. so if you have good fuel pressure , then you say you have good spark, then your problem is either ingition or valve timing, did your dist.come loose, did you properly install chain & gears and align timing marks. did you have somethine else a part on it too like intake, dist, ? get back with me I'll try to help you.

2004 chevy suburban no or very sluggish acceleration when you step on the gas


if you've replaced spark plugs and wires lately, try simply running lucas fuel treatment to your gas, it may be an injector may be clogging or dirty injectors period. if that does'nt work, try replacing the idle control sensor. does it start and die sometimes on it's own? idle rough sometimes? that points to several things, like bad egr valve, is check engine light on?or bad idle control sensor, may be a bad gas cap lid even. if the fuel pressure coming from fuel pump isn't right it will not preform right at all. at least this are some points to look for hope i helped and thanks for choosing fixya.com
