Disconnect the actuator and see if the problem goes away. If it does, replace the actuator. If the problem persists then look at MAP sensor as the possible culprit

SOURCE: 1995 nissan maxima bogging

My 95 did this exactly to a Tee. After trying several things, like cleaning/replacing MAF, fuel injection cleaner to no avail, I ended up unplugging my battery overnight to reset the ECU. The next morning, I put cleaned old MAF and put it back on. Then hooked up battery. Started up, no bogging at 2000 rpms, no stalling, etc. The new MAF was an aftermarket that I bought on Ebay for $86. My car didn't like the aftermarket MAF, so I wouldn't recommend. Anyway, that was 2 weeks ago, and everything is still running good. Hope this helps.

My car 's engine is searching an it strugle's to rev up or while I drive when I apply accelerator the car loses its power

This can be related to a couple of issues, the most common of which are:
1. Fuel delivery problem (e.g. the fuel pump produces too low fuel pressure or the fuel pressure regulator can be shot or the injector(s) may be clogged). When you step on it, it leans out and has no power.
2. Air delivery problem or air metering problem:
- a clog in the air intake (I've once had a mechanic leave a rag in the air filter box and the car wouldn't want to accelerate)
- airflow sensor
- map sensor
- throttle position sensor
3. plus, the searching can be a symptom of a shot idle air control motor (stepper motor), but this won't fix the loss of power so I'd suggest leaving it for later, after the loss of power problem's fixed.

How do u reset the timing on a 1995 chevy monte carlo 3100 engine.

Advice of Haynes manual is worth it . But to answer your Intake ?? if it is intake manifold gasket there are 3 of them . The upper planium is the Aluminum part the Air intake hose attaches TOO - a common GM loss of pressure gasket causing rough idle / drivebility issues . Then # 2 gasket is lower intake mounting to antifreeze carrying Intake manifold same air pressure loss. ## 3 is Intake base mounting to cylinder heads and has coolant carried in it to keep air / fuel mix charge cold . Now U see you did not remove cylinder heads so the Timing belts or heads not have been disturbed = no need to set timing . Timing is set by computer via sensors and Belt Load / Tension under Rpm . If you have loose / worn out Timing belt then engine will rattle when applying power in gear with foot on brake - it may stall under test I described and not want to restart - That would be reason to Look at resetting Timing issues . Good luck .

1999 dodge caravan runs okay until you try to quickly accellerate or when attempting to go up a steeper grade. At these times it pops back through the intake and you lose power The power loss is worse...

have a fuel pressure check ran on the vehicle to make sure it is mantaining the proper fuel pressure at all may be holding enough to keep it running at low acceleration.i hope this helps

Car loses power when it gets to about 80Mph

the boost controller works by vaccum pressure on some turbo engines and if it loses vaccum to the controller it dumps all turbo pressure out exhaust instead of intake. I would check that if it were me. It could be the mass air flow though it is located in the breather tubing somewhere between filter and the intake manifold.
