Engine revs up and down while driving


How is it at idle? A fast idle might be the result of a vacuum leak. Is there a check engine light with a code? Did you clean the mass air flow sensor?

93 chevy suburban v-8 tbi hard to start, but starts, will run but will not idle, can keep it running or driving as long as you rev engine constantly. Holding engine at half throttle it will slow and die. ...


Assuming your engine is in good mechanical condition, there are only a few options.

1. You may have a vacuum leak.
2. The pickup in the distributor may be worn to the point that it is sloppy at idle but normal at higher rpm.
3. Idle control valve/motor may not be working properly.

It probably isn't an ignition related problem as the problem would normally get worse as RPM increases. I've seen #2 about 5 times in the past year or 2 so it's not uncommon and would recommend replacing the entire distributor if you come to that conclusion, but would definitely check all vacuum hoses first.

97 k1500 5.7 liter vortec misses on cylinders 3 and 5 while idling. about 1500 rpm only cylinder 3 and 4 miss then at 2000 rpm only cylinder 4 and 8 miss. what could cause this?


I have had continuous missing issues on my 1997 Silverado after i had a new engine installed 30,000 miles ago. Today I purchased a new gasket for the EGR Valve and removed it. The mechanic had re-used the old gasket when he replaced the engine and cut corners to save $2.00. I found he had installed the EGR bass-ackwards causing my check engine light to stay on and the engine always to miss. Engine runs GREAT now

Will idle high sometimes up to 3000 rpms when driving or sitting still


I have the same Jeep and same problem. The engine was running rough. The Jeep dealer fixed a vacum problem in the manifold and they then decarbonized and cleaned the fuel injectors. After these repairs the idle problem began, it would spike to 2000 rpm while sitting at idle, sometimes it would slowly come down, sometimes I would have to tap the accelerator. I took it back in and they then replaced the throttle motor and reprogrammed the PCM (Power Control Module?) Still same problem. Now they suspect a another vacuum leak and I am taking it back in on Tuesday, will let you know what happens, $ 1,300 so far.

Won't start, engine wont rev above 2000rpm


Have the alternator tested. You are providing a low charge to the battery when you jump it and when taking it above 2K RPM requires more amperage resulting in the engine dying and the rough idle

I have 2000 V8 LS thatruns rough in park and at idle in drive.


That is normal.
If you rev it in park it will not rev over 3500 rpm before it hits the rev limiter.
