Question about 1987 Chevrolet Camaro

The runs fine when in park or neutral. When you

The runs fine when in park or neutral. When you shift to drive or reverse it runs extremely rough and most of the time will stall out. If can get it to move, the RPMs go way high, quickly and the car does change gears as it should. Please help me, I bought this as a project car for my son's HS graduation and would love for him to be able to drive it to college while we restore it.

Try clean out the throttle body with two cans of throttle body cleaner, follow the instructions on the cans and pay attention to the idle air control valve which controls the idle of the engine while in park or in gear. It's common for carbon to build at the valve and cause issues such as the oe your getting and also the EGR valve will have the same effect, but you can use carb cleaner on the EGR valve. Locate the EGR valve, remove it and clean it out with carb cleaner and make sure that there is no binding to the valve it self and place it back. These are the most common solution to your stalling issues, Recap, clean out the throttle body as much as you can and pay attention to the idle air control valve and passage ways and clean out the EGR valve. Once all has been cleaned out turn the ignition key's to the on position for 30 seconds and then turn the keys off, then turn the keys on for 10 seconds and then start and let idle for 1 min then go for a test drive. This will reset the idle air control valve and you have to do it again if it still not idling right, most of the time it will idle high then come down. That is normal, take note also that use only throttle body cleaner on the throttle body, the carb cleaner is to corrosive to the gaskets used in the throttle body. You can use the carb cleaner on the EGR valve which is stronger, then other thing to that is good is to run a product SEA FOAM, which you can buy at most auto parts store. Warning there will be lots of smoke so please look at you-tube and search Sea Foam so you know how much smoke will come out of the tail pipe, but it will clean out the upper intake of most of the carbon built up and then go for a test drive out on the high way to ensure you burnt out all of the Sea Foam. Good luck and hope this helps. As for your project here is a few things you can do other then replacing the spark plugs and wires and rotor and caps, don't forget to service the transmission and rear end too. Good luck friend and keep me posted, be glad to help you get your car running 110%

    And almost forgot, if you have an automatic and when you have the transmission serviced. Have then replace the servo's with corvette servo's, there only $45.00 and you don't have to drop the valve body or the transmission oil pan. It takes about 30 min to do so you can have the transmission shop replace it for you the same time you have the transmission oil and filter changed. your going to be more happier and your transmission will last longer. I have 1996 jimmy with the corvette servo's since two weeks after i bough it and it's now running 341,000 miles with the same transmission with a better shift. LOL. Good luck and be safe.

My trail blazer will shift to park reverse and neutral but not to drive


Have someone check your motor mounts and your shift linkage for wear, binding, and or damage from car accident or from foreign object under the car.
Problem should be in one of those areas.

When I try to shift from park to drive it gets tight at reverse as if doesn't want go but once out of reverse it shift normally until shifting back to park when I have to go threw reverse then it tightens...


Is it only when you go from park to reverse? Or is it just as bad going from neutral to reverse? I've noticed on mine that it's often tight if I park on even a slight slope. If it only happens when going from park to reverse, try this. Hold your foot on the brake, and put the car in drive. Keeping constant pressure on the brake, go back to park, then back into drive. Did you feel the stiffness when you had your foot on the brake?

84 crx starts fine and idles fine in park and neutral, but dies immediatly when shifted to drive or reverse. Will run very roughly if pumping accelerator. What's going on?


You might want to check the engine for a vacume leak.Once the rpm's drop it may have a big enough vacume leak to not keep it running under a load.

What engine? Rear wheel drive ?Sounds like shift linkage or cable out of adjustment slightly. Have a look at where cable or rod attaches to transmission for adjustment. If not sure of what your looking for get back to me with info.
