Chevy 350 surging rpms

My pickup's rpm's surge at around 1750 to 2000 when at highway speeds (65-75mph). O'reilly Auto ran error codes in response to check engine light on. There were 4 different "solutions" to the problem and I am hoping to narrow it down even further. I have had this problem for a few years. The problem comes and goes but it tends to be more prevalent during hotter, longer running drives (Summer months). The truck runs fine aside from that.

Go to your local shucks or auto zone and they can check any codes behind your check engine light and it's free. It sounds like one of two things a O2 sensor or your mass airflow sensor but they will tell you for sure

2003 protege surges in rpm


When you say " surges in rpm" you mean it surges when you give it gas, press down on the accelerator. It could any one of a dozen reasons for this; dirty air filter, dirty gas filter, foiled spark plugs, ignition problems, faulty fuel regulator faulty speed sensor, etc. Have the car's computer scanned for trouble codes which will identify where the problem is. Auto Zone and Advance Auto will do a scan.

22r carb dumping fuel at 2500 rpm will not pass smog.Was rebuilt and is in smog specs. at idle.


Fill the tank up but do not top off.

Ran the trunk for 15-20 minutes on the highway and recheck the fuel surge condition at 2500 rpm.

If it stop surging then you has a weak fuel pump.

Change the fuel filter will also help.

Also check the fast idle setting.

If everything checks out then set a smog check appointment in the EARLY MORNING.

96 Jeep Cherokee RPM Surge While Driving


If the problem began before you changed the plugs that they are likely OK...Some engines "like" certain brand plugs better than others. You may have a weak ignition coil. Poor spark will generally show up at higher rpm's. Spark should be blue and have good "snap" to it and should easily bridge a 1/4" gap or better. If fuel was contaminated, it should show up at lower rpm's as well. System cleaners sometimes work but often are added far too late to do any good. (tank can hold up to a gallon of water without noticing it.) I use 3oz of acetone and one oz marvel oil per 10 gallons of fuel about once a month...cheaper and more effective than most cleaners. (and does not "melt" gaskets and seals as legend has it) The vehicle speed sensor can also give you problems but needs testing to determine if it's got any problems.
It's difficult to diagnose by remote control, but I hope you benefit form something here!

Engine surges at rpm over 1500


Look for a vacuum leak (lines and intake), Is the engine light on, were any codes present? A faulty EGR or IAC could cause the problem too. Check the throttle cable for any restrictions.

1995 toyota pickup, surging at around 2000 rpms


Is the check engine light on?

A major cause of surging is either air leaks between the air flow meter and the engine intake manifold, or a bad or mis-adjusted throttle position sensor.
