Rough idle and fluctuating rpms, no power when in gear,runs rough

When starting my car it will run as smooth as ever until I place it in Drive or Reverse or if I take my foot off the gas the RPMs will fluctuate up and down and idles really rough. The check engine light is blinking. Any suggestions?

Check for vaccume leaks and also you PCV valve. check the hose too. Visually inspect every vaccume hose you can find. Sounds like a leak .

This make/model has a chronic problem with EGR clogging. If you have a dashboard indicator showing "check engine" most likely it is a trouble code indicating and EGR (exhaust gas recirculator) valve problem. Symptoms are rough idle, and surging and stalls.

What happens is sediments from the exaust manifold get sucked up into the valve when it opens, then stick in the valve and keep it from closing. When the valve is open when it should be closed, the engine runs very rough.

I removed my egr and then dislodged the sediment (pea-sized debris) and then re-installed the valve. Three days later, the same "check engine" and same rough idle. I must have did this at least three or four more times.

What I found that gave me a permanent solution was an aftermarket filter gasket that keeps debris from clogging. I don't remember the name of the product, but a search for "EGR filter gasket" may lead you to the product.

Install the gasket between the EGR and the exhaust manifold and you should be good to go. Note: on 1995 and newer models, disconnecting the EGR from the wiring harness (common on R&R) may require the computer to be reprogramed.

could be a number of things. timing may be off. timing chain could have jumped but then you would have lack of power and backfire. could have a vacuum leak. throttle body have carbon buildup around the butterfly valves? Valve problems. compression problems. many things. Hope its nothing major I know I am not being much help but those are some things to look at.

How will I adjust the rev of carburetor when aircon is on?


you don't adjust the idle for any accessories
The idle is set for smooth running of the engine( normally 750-900 rpms with a drop of 200-300 rpms with an ac running so set the idle at the upper rpms and it will still be smooth when the ac is on without affecting gear engagement
your problem I take it is that when the ac cuts in the idle rpms drops and makes the engine run rough
This is normal as the ac compressor takes up to 5 hp to drive it
what you need is an electric controlled vacuum pot connected to the accelerator lever so that when you switch on the ac the power to the ac clutch energizes the pot and vacuum pulls the accelerator lever to maintain the set idle rpms
such an item is found on most early carby operated engines

I think your car has a 7th injector called a cold start injector. Takes the place of a choke. If it does check n make sure it's working properly. That's all I can think of at this time. Hope it helps. Also sounds like you still have a pretty bad vacuum leak. Listen for hiss at idle. Good luck
