1993 Chevy Cheyenne Ignition hesitation

Hi bayouparson,

Thank you for the donation.

We need to understand the problem better in order to assist in rectification and would like to ask a few questions. As we progress we might need to ask more questions.

When the problem happens, how long does it last?

Dos it happen each and every time it reaches the speed?

Does it happen if OD is turned OFF? Does it happen at a lower speed with OD OFF?

Any Check Engine Light showing?

Are you mechanically inclined and would be doing the rectification by yourself?

Hi Jerry,

Thank you for the answers.

Yes, OD mean the Overdrive. What I am trying to establish is if this is an engine or trans related problem.

If it is possible, I would like you to note the engine rpm at the speed it is hesitating. Turn the OD off and try to run vehicle at lower speed with engine rpm similar to with Od on. Note if problem arises.

For auto trans, engine hesitation usually are not felt as the torque converter is able to reduce the impact and if it is felt, the hesitation should be quite bad.

When the hesitation appears, does it occurs repeatedly while you maintain the speed range?
Does it happen only when you are accelerating or does it happen even while cruising, maintaining constant accelerator pressure?

How long has this problem been going on and what have you done before and after it has been noted?

When was the auto trans fluid last checked? How was its level and consition?

What is the engine type on your vehicle?

Sorry you did not provide me with details of the engine type. There are many variations and the specific type helps.

Seems strange for the trans fluid to stop leaking by itself. Possibility could be due to overfilling where it flows out throught the overflow hose and now that level is down, it stops.

Does it happen only when the cruise is being set?

Sorry for getting back to you late. I was trying to source for additional info and seems to come to a dead end.

When replying to a post, if you scroll down slightly, you can review the topic and previous post.

From the symptoms described, it could be rpm related when throttle pressure is released.

I am not able to relate it to any possible cause as it does not happen at other speeds and you are not able to gauge the engine rpm at that instant.

Under such circumstances, the best option is to install diagnostic equipment and test drive to monitor the condition under which it happens, you might be able to note the malfunctioning condition and get an idea where tje problem is coming from.

When was the last time you checked the engine tuning components such as spark plugs, etc?

Since noticing the problem is it getting more frequent and and is it with increased intensity?

You are welcomed but I feel bad not being able to help you solve the problem yet. Thank you for being so understanding.

Even with physical vehicle it is not easy to diagnose and rectify some problems so diagnostic equipments are a neccesity nowadays.

Keep me posted of the outcome.

Thank you and have a nice day. It has been a pleasure corresponding with you.
