First off I'm going to say that I'm not a mechanic and far from it. The little bit I know about cars is from learning to fix my own. I have a 93' 2.3L Convertible. When i first got the car about 3 years ago everything seemed fine. At a dead stop she accelerated nicely and ran like a champ. After about a year or two of having the car i began working as a pizza delivery driver so I was driving it everyday.
About 3 months ago while on a delivery I was pressing the gas as i was pulling out of a driveway and as i pulled onto the road and pressed the gas to go faster it hesitated and completely refused to go any faster.
This was off and on for awhile. Hesitating, Misfiring, piss poor acceleration and almost a complete loss of power. Even when the car is wanting to go and im on the highway if there is a incline i slow down greatly. sometimes going 70mph then down to 30, Not safe. At a dead stop sometimes the lack of acceleration will either just cause me to slowly, i mean SLOWLY, pick up speed or make me pull over to get out of traffic. Obviously it made me loose my job. (Loosin a pizza delivery job, sad right) After that i didnt run my car to much but the symptoms where still there. Desprate to fix it with little to no money i did some maintnence myself.
I changed spark plugs and wires, fuel filter, air filter, cleaned the MAF, and replaced the TPS. Still no luck :fuming:Tho after cleaning my MAF it seems to slightly accelerate faster and act better as long as im going under 50mph. above that it tends to still mess up.
Additional detail if needed:
Idles around 1k sometimes lower. Friend informed me this is low but im not sure
Also, when the car is messing up i usually pull over for a few minutes and im able to drive it better for awhile before it messes up.
2 Cats on a single exhaust and the second one is gutted because it was messed up
Also how can i check to see if the CANP (Canister Purge Selenoid) is ok or needs to be replaced?
