    everything looks dry, could there be a timing issue, or what possible conditions that would lead to this?

Engine stalling when i step on gas petal. Idles great, just acts like its gonna stall when i give it more gas????? cuts out around 2000rpm???


check the distributor cap,, clean any corrosion that's in the cap,, clean off the rotor tip,, you may need a new set of plugs, and or wires , if these don't fix the issue,, get some carb cleaner and spray it into the carb or throttle body of your motor, and check the idle control sensor in your vehicle

My gas petal is sticking while drving and it is getting worse.


Are you going to wait until you kill someone or are you going to take it to a mechanic and have the sticking part located and fixed? There is no magic word to be found here which is going to accomplish that feat. Needs hands and eyes on the vehicle. It is a pedal.

When I first start the cars it stalls unless I pat the gas petal a couple of times. Then its okay


this is caused by a slugeged up idle speed control valve and throttle valve, do the following to clean it.
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Two problems. When driving, going from 50 to


2 things to check.
1) make sure the fuel filter is new /air filter also clean.
2) Being a 94 your catalitic converter my be cloged. Check the exhaust flow out of your tail pipe while someone pushes down on the gas petal the flow should increase as the petal goes down. I put a high-flow type on my 2001 with only 44000 miles on it.
I hope this info helps you.

1995 Honda Accord stalls when you do not press the gas petal


Sound like a clogged or defective IAC. (Idle Air Control) It's usually part of the throttle body assembly. It can be removed and the passage ways cleaned out with old fashion carburetor spray cleaner. If that doesn't help you may try replacing the IAC to see if that solves the problem.

Rough idle


a cheap and easy thing to try is to clean the carbs. get some carb cleaner and run through your next tank of gas. Also a batch of bad gas can cause the problem too.

Here is what you need to do, a cleaning of the intake throttle blade and the idle speed control air-bypass valve, they get full of gunk over the miles and cause idle issues (stalls) like yours,
Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the engine at idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Try checking the snorkel tube between the air cleaner and the intake. Open the hood, and have a friend try to rev the engine, and watch the tube...my '92's was collapsing and starving the engine, couldn't get more than 3500-4000 rpm. Could also be a fuel pump problem like low pressure or bad line.
